Question
A crate weighs 750 N. If a simple machine can lift the crate with a force of only 250 N, what is the mechanical advantage of the simple machine?Multiple choice question.0.335001,0003.0
Solution
The mechanical advantage of a machine is calculated by dividing the output force (the force it is able to exert on a load) by the input force (the force that is applied to it).
In this case, the output force is the weight of the crate, which is 750 N, and the input force is the force required to lift the crate using the machine, which is 250 N.
So, the mechanical advantage is calculated as follows:
Mechanical Advantage = Output Force / Input Force Mechanical Advantage = 750 N / 250 N Mechanical Advantage = 3.0
So, the mechanical advantage of the simple machine is 3.0.
