A shovel performs several different functions. One of these is that it gives mechanical advantage as a lever. When does it act like a lever? (1 point) Responses

A. when you push the shovel downward into the dirt and a small force allows you to push down into the dirt easily

B. when the shovel is in the dirt and you push down against the end of the shovel, making it pivot

C. when the soil is lifted with the dirt at the end of the shovel and a lifting force at the handle

D. when you step up onto the shovel with both feet to use your body weight

is the answer c?

1 answer

The correct answer is B. when the shovel is in the dirt and you push down against the end of the shovel, making it pivot.

In this scenario, the shovel acts as a lever. The handle serves as the lever arm, the pivot point (fulcrum) is where the shovel is in contact with the ground (the dirt), and your downward force at the handle allows the shovel to lift the dirt from the end.

While option C mentions lifting the soil, it does not specifically describe the lever mechanism in action as clearly as option B.
