Chapter 9, Problem 18A
In which type of lever is the output force smaller than the input force?
Expert Solution & Answer
To determine
Type of a lever is the output force smaller than the input force.
Explanation of Solution
Introduction:
There are three types of lever. This types are depends on the location of input force, load and the fulcrum.
In type 3 lever a load is placed at one end, fulcrum is placed at other end and input force is in between them. Load and fulcrum are at greater distance due to which load will travel a greater distance than when input force is applied. Output force is smaller due to this greater distance travelled by the load.
Conclusion:
The lever of type 3 in which output force is smaller than input force.

- For each of the actions depicted below, a magnet and/or metal loop moves with velocity v→ (v→ is constant and has the same magnitude in all parts). Determine whether a current is induced in the metal loop. If so, indicate the direction of the current in the loop, either clockwise or counterclockwise when seen from the right of the loop. The axis of the magnet is lined up with the center of the loop. For the action depicted in (Figure 5), indicate the direction of the induced current in the loop (clockwise, counterclockwise or zero, when seen from the right of the loop). I know that the current is clockwise, I just dont understand why.
