Answer 1

Based on the data provided, the mechanical advantage of the lever is 4.67.

What is the mechanical advantage of  the lever?

Mechanical advantage of the lever is given by the formula below:

• Mechanical advantage = input distance/output distance  OR
• Mechanical advantage =  effort arm//load arm

For the given lever:

Input distance/effort arm = 2.8 m

Output distance/load arm  = 0.6

Mechanical advantage =  2.8/0.6

Mechanical advantage = 4.67

Therefore, the mechanical advantage of the lever is 4.67.
