Question 30
Easy

Figure 1 shows a craft worker using a heavy-duty paper trimmer (guillotine) to cut thick cardboard.

The load is the resistive force of the cardboard resisting the blade.

The effort is the downward force the worker applies to the handle.

Diagram of a heavy-duty paper trimmer. A cutting blade is attached to a board by a hinge on the left, labeled 'pivot'. A sheet of cardboard is positioned on the board near the pivot; a downward arrow labeled 'load' shows the resistance of the cardboard. An arrow at the far right end of the handle points downwards, labeled 'effort'.

Explain why the effort force needed to cut the cardboard is smaller than the load force.
