Question

How does the shovel make work easier for the man digging the hole? Check all that apply. The shovel changes the direction of the force the man applies. The man can apply less force. The man has to apply more force. The force applied by the end of the shovel decreases. The force applied by the end of the shovel increases.

Answer 1

A shovel allows a man to apply less force when digging a hole by increasing the force at the end of the shovel due to the lever action, making work easier without changing the direction of the applied force.

Step-by-step explanation:

The shovel is a type of simple machine, specifically a lever, that makes work easier for the man digging the hole. It does this by changing the amount of force he must apply to accomplish the task. When using a shovel, the man can apply less force than if he were using his hands alone due to the mechanical advantage offered by the tool.

The pivot point of the shovel acts as the fulcrum, and the length of the handle provides a lever arm. When the man applies a force to one end of the shovel, the opposite end, where the load is, experiences an increase in force. Therefore, the force applied by the end of the shovel increases. This is because the input arm is shorter than the output lever arm, allowing the user to lift heavier loads with less input force. However, a shovel does not change the direction of the force the man applies.

Answer 2

1)The shovel changes the direction of the force the man applies.2)The man can apply less force.3)The force applied by the end of the shovel increases.
