What is the primary function of a governor in a mechanical system?
Answer: B. To regulate and limit operating speed
A governor automatically regulates the speed of an engine or machine, preventing it from exceeding a set maximum by adjusting fuel or throttle input.
In a pulley system, what is the mechanical advantage of a single fixed pulley?
Answer: B. 1
A single fixed pulley only changes the direction of the force, not its magnitude. The mechanical advantage is 1, meaning the effort required equals the load.
An inclined plane is 10 feet long and 2 feet high. What is its mechanical advantage?
Answer: B. 5
The mechanical advantage of an inclined plane equals the slope length divided by the height: 10 ÷ 2 = 5.
A screw has a pitch of 2 mm (the distance it advances per full rotation). If a force of 10 N is applied at the end of a screwdriver handle with a radius of 4 cm, what is the approximate mechanical advantage of the screw?
Answer: C. 126
The mechanical advantage of a screw equals the circumference of the handle divided by the pitch: MA = (2π × 0.04 m) / 0.002 m ≈ 0.2513 / 0.002 ≈ 126.
