A block placed under the head of the claw hammer as shown greatly facilitates the extraction of the nail. If a 40-lb pull on the handle is required to pull the nail, calculate the tension T in the nail and the magnitude A of the force exerted by the hammer head on the block. The contacting surfaces at A are sufficiently rough to prevent slipping. T=? Lb. A=?Lb.
