Question

A body of 15 tonne is placed on an inclined plane making 30° with the

horizontal. Find the reaction of plane on the body and also the

effective downward force which will tend to slide the body.​

Answer 1

Answer:

A block of mass M= 10 kg is placed on an inclined plane, inclined at angle θ=37

0

with the horizontal. The coefficient of friction between the block and inclined is μ=0.5.

a. Calculate the acceleration of the block when it is released.

b. Now a force F= 75 N is applied on block as shown. Find out the acceleration of the block. If the block is initially at rest.

c. In case (b), how much force should be added to 75 N of force so that block the starts to move up the incline.

d. What is the minimum force by which 75N force should be replaced with so that block does not move?
