Question

In which of the following class of levers distance moved by the load is always greater than distance moved by the effort?

• A. First class lever
• B. Second class lever
• C. Third class lever
• D. Both first and second class

Answer 1

Answer: (C)

Third class lever

$\text{Solution}$;

1. The mechanical advantage of a 3rd class lever is always less than 1.

2. For this class of levers, the input effort is higher than the output load, which is different from second-class levers and some first-class levers.

3. However, the distance moved by the load is greater than the distance moved by the effort

$\text{Hence C is the correct option}$
