Question
3/5 Three cables are joined at the junction ring C. De-
termine the tensions in cables AC and BC caused by
the weight of the 30-kg cylinder.
3/6 A block placed under the head of the claw hammer
as shown greatly facilitates the extraction of the nail.
If a 50-lb pull on the handle is required to pull the
nail, calculate the tension T in the nail and the mag-
nitude A of the force exerted by the hammer head on
the block. The contacting surfaces at A are suffi-
ciently rough to prevent slipping.
