Question
A box weighing 76.88N. rests on a table. A rope tired to the box runs vertically upward over a pulley and a weight is hung from the other end (Fig 4-40). Determine the force that the table exerts on the box if the weight hanging on the other side of the pulley now weighs 60.69N. One 7.61kg paint bucket is hanging by a masses cord from another 7.43kg paint bucket, also hanging by a massless cord, as shown in Fig. 444. One 6.34kg paint bucket is hanging by massless cord from another7.17kg paint bucket, also hanging by a massless cord, as shown in Fig. 4-44 If the buckets are at rest, what is the tension in the bottom cord?Explanation / Answer
as per chegg guidelines i can answer only one
1)W1=76.88N
Force exerted by thetable on the box wil be
= W1 - W2
= 76.88 - 60
= 16.88 N ( upward )
