A boy pulls a friend sitting in a home-made trolley by means of a rope inclined at 30 to the horizontal. If the tension T in the rope is 300 N, find (i) the effective force pulling the trolley and (ii) the force tending to lift the trolley off the ground.

Text Solution

Verified by Experts

(i) Effective force pulling the trolley
`=F cos theta = 259.8 N`

(ii) Force tending to lift the trolley off the ground would be `mg -F sin 30^(@)`

Find the total number of carts (N) and tension in the last string.

    A student tries to raise a chain consisting of three identical links. Each link has a mass of 300g. The three-piece chain is connected to a string and then suspended vertically, with the student holding the upper end of the string and pulling upward. Because of the student's pull, an upward force of 12 N is applied to the chain by the string. (a) Draw a free-body diagram for each of the links in the chain and also for the entire-chain considered a single body. (b) Use the results of part(a) Newton's laws to find (i) the acceleration of the chain and (ii) the force exerted by the top link on the middle link.
