Question
A family is moving from Pennsylvania to Connecticut. The movers are using a ramp to load boxes onto the truck. The advantage of the ramp is to reduce theSelect one:time needed to raise the boxes by reducing the distance the box is movedhighlight_offwork needed to raise the boxes by increasing the distance the box is movedhighlight_offforce needed to raise the boxes by increasing the distance the box is movedhighlight_offeffort needed to raise the boxes by reducing the distance the box is moved
Solution
The correct answer is: force needed to raise the boxes by increasing the distance the box is moved.
Here's why:
A ramp, also known as an inclined plane, is a simple machine. It allows for the same amount of work to be done with less force over a longer distance. In this case, the work being done is moving boxes up into the truck.
Without the ramp, the movers would have to lift the boxes straight up into the truck, which requires a lot of force. With the ramp, the boxes can be moved up the incline, which requires less force. The trade-off is that the boxes have to be moved a greater distance (the length of the ramp) compared to lifting them straight up.
So, the ramp reduces the force needed to raise the boxes by increasing the distance the box is moved.

A 6.0 m ramp runs from a sidewalk to a porch that is 2.0 m above the sidewalk. What is the ideal mechanical advantage of this ramp?
You are trying to lift a heavy file cabinet into the back of a truck. The file cabinet weighs 200 pounds (about 900 newtons) and you must raise it 2 feet (about 0.6 meters) upward. The file cabinet has wheels, so it rolls freely. You create a ramp using rigid boards that are 8 feet long and successfully push the wheeled file cabinet up the ramp and into the truck. What force did you exert on the file cabinet to keep it moving up the ramp at constant velocity? [Assume the ramp was smooth, straight, and exactly 8 feet long, and neglect any imperfections, such as friction, air resistance, or rotation of the cabinet's wheels.]1 pointYou exerted a force of 25 pounds directed uphill along the ramp.You exerted a force of 50 pounds directed uphill along the ramp.You exerted a force of 100 pounds directed uphill along the ramp.You exerted a force of 200 pounds directed uphill along the ramp.
The roadies at a music concert have to get a piano weighing 2500 N onto a stage 1.5 m high. They have a 6 m-long ramp.Calculate the ideal mechanical advantage of the ramp.With the piano on a small trolley they have to exert 700 N force to push it up the ramp. Determine the actual mechanical advantage of the ramp.Is the actual mechanical advantage greater than, less than, or the same as the ideal mechanical advantage? Explain why this would be.In a world with no friction, calculate the effort force the roadies would need to apply to get the piano up the ramp.Note: Show your calculations.
