Introduction: The pedal of a bicycle is attached to a crank arm that revolves when thepedal is pushed by a person’s foot. As the crank arm turns, it pulls a chain that isattached to the rear wheel of the bicycle, causing the bicycle to move forward.
A particular bicycle has wheels that are 66 cm in diameter. The radius of the crank armis 18 cm. At its lowest point, the pedal is 16 cm above the ground. A person is pedalingthe bicycle such that the crank arm rotates once every second.
Questions:4. Determine an equation that would model the foot’s position when the cyclist istraveling 5 km/h. Compare this equation to your equation from question 1 andexplain any differences.5. Use calculus to explain why the rotation velocity of a point on the perimeter of awheel is the same as the velocity of the pedal. Use examples to support youranswer.

Find the motor size needed to provide the forced-draft service to a boiler that burns coal
at the rate of 10 tons per hour. The air requirements are 59 000 cfm, air is being provided
under 6 inches water gage by the fan that has mechanical efficiency of 60 %. Assume fan
to deliver at a total pressure of 6 inches water gage.

a.
What is the ideal mechanical advantage of this
system? The inclined plane dimensions are 7.2 meters
length and 1.8 meters height.
What effort force is required to move the 600N
create?
In practice, you need to supply an effort force
of 75 N to lift the crate. What is the efficiency?
C.
How could you redesign this compound
d.
machine so that the effort force needed was 50 N in
practice? Assume the efficiency is your response from
part C no matter what changes you make. Be specific
with the changes you propose (if you add pulleys state
how many, if you change the inclined plane
dimensions state the new dimensions, etc.).
