If the force on the cable AD is 664 N, what is the angle of orientation with respect to the x-axis and y-axis of the wire in bolt D (θD.x and θD.y)? (degrees) Given: y = 20 m XB = XD = 2.4 m ; Xc = 8.3ZB = 4.2 m ; ZC = 2.3 m ; ZD = 10.2 marrow_forwardIt is common to hang objects on doorknobs and over-the-door hooks. There is a limit to the amount of weight that a door can hold because of the forces exerted on the hinges. A door of height h = 2.5 m and width h/2 has a mass of M = 36 kg. The mass is distributed uniformly, so the center of mass is located at the geometric center of the door. One hinge is located a distance h/4 from the top of the door. The second hinge is a distance h/4 from the bottom of the door. Refer to (a) in the figure. The door’s weight is supported entirely by the two hinges and each hinge supports half of the weight. In other words, the vertical force exerted by each hinge is exactly one half of the total weight, including any additional load. For this problem, take the positive y-direction to be directly upward and the positive x-direction pointing from the hinge side of the door to the knob side. 1.) calculate the force, with its sign in Newtons that the upper hinge exerts on the door in the x axis.…arrow_forward
