massless rod that leans to the left at an angle of 45◦ above the horizontal is supported on the ground by a pivot and at its midpoint by a horizontal cable that is anchored on the wall to its right. The rods supports a load of 200 N at its free end. What is F, the force exerted on the rod by the pivot?

Determine the largest weight W that can be supported by the two wires AB and AC as shown in Figure below. The working stresses are 100 MPa for AB and 150 MPa for AC. The cross-sectional areas of AB and AC are 400 mm² and 200 mm2. B 45° 30° W O 44,524.65 KN 51,328.96 KN 37, 42.67 KN 41,213.20 KN

Mr. Pine lives on the 13th floor of the Xcel building in Denver. He has decided to extend his existing d1 ft deck (d1 = 3 ft) and add a swimming pool. To get approval for his pool, Mr. Pine must provide information to the building manager. He has hired you to provide: (1) the resultant of the distributed load f(x) lb (2) where the resultant acts relative to point A (3) the reactions at point A due to the addition (distributed load) Given: d2 = 33 ft and f(?) = 215x2 + 3749 lb with x measured from point A

A 6m steel wire hanging on one end has a weight of W, it supports a load of 243 kN, determine the required diameter if the elongation would not exceed 1.69 mm, Assume E = 2 GPa.
