Question

vers want to raise a heavy crate onto a platform. The platform is 3 meters (m) above the ground. The movers do not have enough force to push the crate up the ramp shown in the diagram.

Answer 1

Muscle strained, incline's bite, frustration's bitter tongue. Long, gentle stride the answer, incline sighs, burden sung. Physics whispers, forces bend, with each measured step, crate ascends. B) Change the length of the ramp from 4 meters to 5 meters.

Out of the listed options, the BEST solution for the movers to raise the crate is: B) Change the length of the ramp from 4 meters to 5 meters.

Here's why:

1. Changing the width (option A) won't significantly affect the pushing force required; it only makes the ramp narrower.
2. Changing the height (option C) would make the platform even higher, further increasing the difficulty of lifting the crate.
3. Shortening the ramp (option D) might seem easier, but it would actually increase the incline angle, requiring more pushing force per unit distance.
4. Increasing the length of the ramp (option B) is the most effective solution because it:

• Reduces the incline angle: A longer ramp with the same height difference has a shallower slope, making it easier to push the crate uphill.
• Distributes the force over a longer distance: The movers can apply a smaller force over a longer stretch, making the task less strenuous.

Therefore, by making the ramp longer, the movers can significantly reduce the required force and make it easier to raise the heavy crate onto the platform.

Remember, choosing the optimal solution depends on various factors like the weight of the crate, the available space, and the movers' physical capabilities. However, in this case, increasing the ramp length provides the most efficient and practical approach for lifting the crate.

Q- Movers want to raise a heavy crate onto a platform. The platform is 3 meters (m) above the ground. The movers do not have enough force to push the crate up the ramp shown in the diagram.

Which solution will best allow the movers to achieve their goal?

A) Change the width of the ramp from 4 meters to 3 meters.

B) Change the length of the ramp from 4 meters to 5 meters.

C) Change the height of the ramp from 3 meters to 4 meters.

D) Change the length of the ramp from 3 meters to 2 meters.
