The IMA of a lever can be increased by decreasing the length between the applied effort and the pivot.

We never really used the acronym "IMA", or ideal mechanical advantage, but I'm assuming you are trying to increase the leverage and ease the effort. If so, the answer is false. You want larger movement on the effort side, and smaller movement on the resistant side of the fulcrum.

Explanation:

The ideal mechanical advantage of a lever is defined as the ratio of applied resistance force to the applied effort force. It can be also defined as the ratio of effort arm to the load arm. It is given by :

[tex]IMA=\dfrac{d_1}{d_2}[/tex]

[tex]d_1[/tex] = effort arm

[tex]d_2[/tex] = load arm

If the length between the applied effort and the pivot is decreased, the IMA of a lever will decreased. This is due to the direct relation between IMA and effort arm. So, the given statement is false.
