Question

A spur gear has a module m=1.125 mm/ tooth and 200 teeth. What is the pitch diameter of the gear?

a. 7.2 cm
b. 17.8 cm
c. 22.5 cm
d. 5.7 cm

Answer 1

The mechanical advantage of the car in this simplified model is 0.04. Hence , the mechanical advantage of the car is 0.04.

Step-by-step explanation:

The mechanical advantage of a system can be calculated by dividing the radius of the axle by the radius of the tire. In this case, the axle radius is 1.10 cm and the tire radius is 27.5 cm.

Therefore, the mechanical advantage is:

Mechanical Advantage = Axle Radius / Tire Radius

Mechanical Advantage = 1.10 cm / 27.5 cm = 0.04

So, the mechanical advantage of the car is 0.04.
