Term1/11

What is the mechanical advantage of a ramp What is the mechanical advantage of a ramp standing straight up

Term1/11

What is the formula used to calculate mechanical advantage

Definition1/11

Mechanical advantage=load/effort

Term1/11

What is the Ideal Mechanical Advantage when a screwdriver with a handle of radius 1.2 cm is used to remove a screw in the back of a computer and the screw moves out 0.20 cm on each turn

Definition1/11

There is no advantage whether the handle is 1.2 cm or 10 cm, the screw will still only make one revolution. The reason being is that both the screw driver and the screw become part of the whole. The only increase in the screws revolutions is if the screw driver is geared to make more than one turn of the screw.

Term1/11

How do you calculate the work done on a object

Definition1/11

To calculate work done on an object one needs to use the following equation; work = force x distance or W = F x d
