4. A block placed under the head of the claw hammer as shown greatly facilitates the extraction of the nail. If a200-N pull on the handle is required to pull the nail, calculate the tension T in the nail and the magnitude A ofthe force exerted by the hammer head on the block. The contacting surfaces at A are sufficiently rough toprevent slipping.200 N200 mm2045 mm50 mm

The bell-crank mechanism is in equilibrium for an applied load of F1 = 11 kN applied at A. Assume a = 250mm, b = 100mm, c = 90mm, and θ = 40°. Pin B is in a double-shear connection and has a diameter of 29 mm. The bell crank has a thickness of 31 mm. Determine the shear stress in pin B and bearing stress in the bell crank at B. Express your answer in MPa rounded to the nearest hundredths.
Problem 04.107 - Maximum load carrying capacity of a milled rod with known allowable stress A milling operation was used to remove a portion of a solid bar of square cross section. Knowing that a = 30 mm, d = 20 mm, and all = 54 MPa, determine the magnitude P of the largest force that can be safely applied at the centers of the ends of the bar. The magnitude P of the largest force that can be safely applied at the centers of the of the bar is KN.
