With a pulley system, a force of only 50 lb can lift a 500-lb weight. What is the mechanical advantage if this system is 100% efficient

Sagot :

Answer:

the mechanical advantage is 10

Explanation:

The computation of the mechanical advantage is as follows:

Mechanical advantage is

= Load ÷ Effort

where,

The Loan is equivalent to the weight i.e. 500 lb

And, the effort is equivalent to the force applied  i.e. 50lb

So, the mechanical advantage is

= 500 ÷ 50

= 10

Hence, the mechanical advantage is 10
