Question

find the tension t needed to hold the cart in equilibrium if there is no friction​

Answer 1

Answer:

Explanation:

HERE IS THE ANSWER FOR YOUR QUESTION;

◆The net horizontal forces must be balanced, since tendency of motion is in horizontal direction.

◆ Assume the tension in string to be T1. Then T1 = Wsin30= W/2.

◆ Now the horizontal component of this force must be equal to tension T.

Therefore, T1cos30=T. Hence, T = root3W /4.
