Question

A lever has a effort force of 5 Newton's and an resistance force of 15 Newton's; what is the mechanical advantage of the lever?

Answer 1

3

Step-by-step explanation:

From the question given above, the following data were obtained:

Effort = 5 N

Resistance = 15 N

Mechanical advantage =?

Mechanical advantage is simply defined as the ratio of the resistance to the effort. Mathematically, it can be expressed as:

Mechanical advantage = Resistance /Effort

With the above formula, we can obtain the mechanical advantage as follow:

Effort = 5 N

Resistance = 15 N

Mechanical advantage =?

Mechanical advantage = Resistance /Effort

Mechanical advantage = 15 / 5

Mechanical advantage = 3
