Question

Increasing the length of an inclined plane [?] the mechanical advantage while potentially improving [?].
Fill in the blanks.

Answer 1

Increasing the length of an inclined plane increases the mechanical advantage while potentially improving safety and control.

Brief explanation: ideal mechanical advantage = length/height, so a longer plane lowers the required input force. The trade-off is you must move the load a greater distance and, in the real world, friction can increase energy losses.
