Determine the weight w2 and the angle a needed so that the leg and the cast do not exert any force on the hip joint.The figure below shows a claw hammer being used to pull a nail out of a horizontal board where ? = 27.3°. The mass of the hammer is 1.00 kg. A force of 165 N is exerted horizontally as shown, and the nail does not yet move relative to the board. Assume the force the hammer exerts on the nail is parallel to the nail. A hand uses a hammer to pull a nail out of the ground. The head of the hammer is curved and touches the ground at a single point of contact at the center of the head. The nail in the ground makes an acute angle ? clockwise from the vertical.

What force will balance the three?You hold up a long pole with a length of 4.0m and a weight of 108N so that it makes an angle of 75° with respect to the horizontal (15° with respect to vertical). In order to do this, you exert forces with both of your hands. One hand is at the bottom of the pole and exerts both horizontal and vertical forces. Your other hand is 0.75m up along the pole as measured from the bottom end of the pole and exerts a purely horizontal force (no vertical component). If the pole is in equilibrium, what are the forces that each of your hands exerts? Be sure to give both components for the force your bottom hand exerts. Include directions for each force component. This is all the information provided, there is no diagram.
