W 20° P 200 mm A 45 mm 50 mm A block placed under the head of the claw hammer, as shown, greatly facilitates the extraction of the nail. If a force 76.5 N pull on the handle is required to pull the nail with a tension W= 800 N, calculate the magnitude of the resulting force at A, where contacting surfaces are sufficiently rough to prevent slipping. Give your answer in Newtons.

Two children push on opposite sides of a door during play. Both push horizontally and perpendicular to the door. One child pushes with a force of 17.5 N at a distance of 0.600 m from the hinges, and the second child pushes at a distance of 0.450 m. What force must the second child exert to keep the door from moving? Assume friction is negligible.
In order to get his car out of the mud, a man ties one end of a rope to the front bumper and the other end to a tee 15 m away as shown below. He then pulls on the center of the rope with a force of 400 N, which causes its center to be displaced 0.30 m, as shown. What is the force of the rope on the car?

To facilitate shifting the position of a lifting hook when it is not under load, the sliding hanger shown is used. The projections at A and B engage the flanges of a box beam when a load is supported, and the hook projects through a horizontal slot in the beam. The connections at A and B are smooth. Compute the magnitudes of the forces at A and B when the hook supports a 200-kg mass Assumem - 200 kg, a-280 mm, b-415 mm. Answers: a N N
