Answer:

S2 = 60 RPM.

Explanation:

Given the following data;

Gear ratio = 40/24 (T2 = 40 and T1 = 24).

Speed of driving gear = 100 RPM

To find the speed of the driven gear;

Mathematically, gear ratio in terms of speed (RPM) is given by this formula;

[tex] S_{1} * T_{1} = S_{2} * T_{2} [/tex]

Where;

Substituting into the equation, we have;

[tex] 100 * 24 = S_{2} * 40[/tex]

[tex] 2400 = 40S_{2} [/tex]

[tex] S2 = \frac {2400}{40} [/tex]

S2 = 60 RPM.

Therefore, the speed of the driven gear is 60 revolutions per minute.

Answer:

I. Inclined plane: GPE to KE.

II. Screw: KE to GPE.

III. Wheel and axle: GPE to KE.

IV. Lever: GPE to KE.

V. Wedge: GPE to KE.

VI. Pulley: GPE to KE.

Explanation:

A simple machine can be defined as a type of machine with no moving parts but can be used to perform work.

Basically, a simple machine allows for the transformation of energy into work. The six simple machines are;

I. Inclined plane: gravitational potential energy to mechanical energy (kinetic energy). It is set at an angle and then used to lift an object.

II. Screw: kinetic energy to potential energy. It is held in position and then used to tighten two or more objects together.

III. Wheel and axle: gravitational potential energy to mechanical energy (kinetic energy). It comprises of two circular objects which aids in the motion of an object such as a car.

IV. Lever: gravitational potential energy to mechanical energy (kinetic energy). It comprises of a pivoted bar at a fixed point (fulcrum) that allows it to be used for lifting heavy objects.

V. Wedge: gravitational potential energy to mechanical energy (kinetic energy). It can be used to split objects into halves.

VI. Pulley: gravitational potential energy to mechanical energy (kinetic energy). It is made up of a wheel and rope which allows force to be multiplied such as in a drawing well.

Energy can be defined as the ability (capacity) to do work. The two (2) main types of energy are;

a. Gravitational potential energy (GPE): it is an energy possessed by an object or body due to its position above the earth.

b. Kinetic energy (KE): it is an energy possessed by an object or body due to its motion.

In science, what exactly is a force?

In science, "force" refers to a certain concept. It is quite acceptable to refer to a force of this level as a push or a pull. It's incorrect to say that an object "has in it" or "contains" a force. A force is experienced by one thing from another. The concept of a force makes no distinction between living creatures and inanimate objects. Force is defined as a push or pull that causes the body it is acting on to accelerate. The unit of force in the SI is the Newton.

Answer:

1) The speed of the roller coaster at the bottom is approximately 15.65 m/s

2) The acceleration of the roller coaster at the bottom is 6·g's

3) The high acceleration is 6 times the force of the weight of the  passengers

The high acceleration can cause gravity induced loss of consciousness

4) Please find attached a force diagram of the forces at the bottom of the roller coaster created with Microsoft Visio

5) For the acceleration at the bottom to be 2·g's the radius of the rollercoaster at the bottom should be 25 meters

5) The radius at the bottom of roller coasters are increased to reduce the normal force felt by the passengers as they pass the bottom of a circular roller coaster

Explanation:

1) The given parameters are;

The radius of the roller coaster, r = 5.0 m

The speed of the roller coaster = Minimum = 0 m/s

The shape of the roller coaster's path = Circular loop

Therefore, the maximum height of the roller coaster, h = The diameter of the of a circular path of the roller coaster, d = 2 × r = 2 × 5.0 m = 10.0 m

∴ h = 10.0 m

The minimum speed is f=given by the following equation;

[tex]F_N = \dfrac{m \cdot v^2}{R} - m \cdot g = 0 \ (At \ the \ top \ of \ the \ roller \ coaster's \ path)[/tex]

Therefore, we have;

[tex]\dfrac{m \cdot v^2}{R} = m \cdot g[/tex]

From which we have;

v = √(R × g)

Where;

R = The radius of the path of the roller coaster = 5.0 m

g = The acceleration due to gravity = 9.8 m/s² = constant

By plugging in the values of the variable, 'R', and the constant, 'g', we get;

v = √(5.0 m × 9.8 m/s²) = 7 m/s

The minimum speed of the roller coaster, v = 7 m/s

The speed of the roller coaster at the bottom is given by the conservation of energy formula as follows;

The energy at the top of the roller coaster = The energy at the bottom of the roller coaster

∴ The total mechanical energy of the roller coaster, M.E., is constant and at the top, [tex]M.E._{top}[/tex], is given as follows;

[tex]M.E._{top}[/tex] = 1/2·m·v₁² + m·g·h₁

At the bottom, the total mechanical energy is given as follows;

[tex]M.E._{bottom}[/tex] = 1/2·m·v₂² + m·g·h₂

Where;

v₁ = The velocity of the roller coaster at the top = 7 m/s

h₁ = The height of the roller coaster at the top = 10 m

v₂ = The speed of the roller coaster at the bottom

h₂ = The height of the roller coaster at the bottom = 0 m

g = The acceleration due to gravity = 9.8 m/s² = Constant

By plugging in the values, we get;

M.E. = [tex]M.E._{top}[/tex] = [tex]M.E._{bottom}[/tex]

∴ 1/2·m·v₁² + m·g·h₁ = 1/2·m·v₂² + m·g·h₂

1/2 × (7 m/s)² + 9.8 m/s² × 10.0 m = 1/2 × v₂² + 9.8 m/s² × 0 m

122.5 m²/s² =  1/2 × v₂²

∴ v₂² = 2 × 122.5 m²/s² = 245 m²/s²

v₂ = √(245 m²/s²) = 7·√5 m/s ≈ 15.65 m/s

The speed of the roller coaster at the bottom, v₂ ≈ 15.65 m/s

2) The normal force on the car at the bottom of the roller coaster is given as follows;

[tex]F_N = \dfrac{m \cdot v_2^2}{R} + m \cdot g = m \times \left(\dfrac{ v_2^2}{R} + g \right )[/tex]

Force, F = Mass, m × Acceleration, a

∴ F = m×a

Therefore, the acceleration at the bottom, 'a' by comparison of the general equation for force, 'F', and the normal force, [tex]F_N[/tex], is given as follows;

[tex]a = \left(\dfrac{ v_2^2}{R} + g \right )[/tex]

Plugging in the values for 'v₂²', 'R', ang 'g', gives;

[tex]a = \left(\dfrac{ v_2^2}{R} + g \right ) = \left(\dfrac{ 245}{5} + 9.8 \right ) = \left(49+ 9.8 \right ) = (5 + 1) \times 9.8 = 6 \times 9.8 = 6 \times g[/tex]

a = 6·g = 58.8 m/s²

3) The high acceleration will lead to a very high normal force (equal to 6 times each of their weight) experienced by the passengers with a force

The high acceleration is dangerous and can lead to gravity induced loss of consciousness since it is more than 3·g's

4) Please find attached the force diagram at the bottom of the roller coaster created with Microsoft Visio

5) For the acceleration at the bottom to be 2·g's, we have;

[tex]a = \left(\dfrac{ v_2^2}{R} + g \right )[/tex]

At a = 2·g, we have;

[tex]2 \cdot g = \left(\dfrac{ v_2^2}{R} + g \right )[/tex]

[tex]\therefore 2 \cdot g - g = g = \dfrac{ v_2^2}{R}[/tex]

[tex]R = \dfrac{ v_2^2}{g} = \dfrac{245}{9.8} = 25[/tex]

R = 25 m

The radius at the bottom of the roller coaster should be 25 meters so that only 2·g's is felt

5) The shape of the roller coaster has an increases the radius at the bottom so as to reduce the acceleration of the car

Answer:6

Explanation: To calculate the actual mechanical advantage (AMA) of a first-class lever, we use the following formula:

AMA = load/effort

In this case, we know that the load (FR) is 180 lb and the effort (FE) is 30 lb. So we can plug these values into the formula:

AMA = 180 lb / 30 lb

AMA = 6

So the actual mechanical advantage of the system is 6, meaning that for every 1 lb of effort applied, the load moves 6 lbs.

The load distance is given as 6 ft, but it is not used to calculate the AMA in this case. The AMA is calculated only from the ratio of load and effort forces.
