assignment is attached as well. pictures and drawing are incluced in such. thanks 1.Workers have loaded a delivery truck in such a way that its center of gravity is only slightly forward of the rear axle, as shown in the drawing. The mass of the truck and its contents is 6170 kg. Find the magnitudes of the forces exerted by the ground on the following. (a) the front wheels N (b) the rear wheels of the truck N 2 In an isometric exercise a person places a hand on a scale and pushes vertically downward, keeping the forearm horizontal. This is possible because the triceps muscle applies an upward force perpendicular to the arm, as the drawing indicates. The forearm weighs 19.0 N and has a center of gravity as indicated. The scale registers 128 N. Determine the magnitude of . N 3. A 1240-N uniform beam is attached to a vertical wall at one end and is supported by a cable at the other end. A W = 1935-N crate hangs from the far end of the beam. (a) Using the data shown in the drawing, find the magnitude of the tension in the wire. N (b) Using the data shown in the drawing, find the magnitude of the horizontal and vertical components of the force that the wall exerts on the left end of the beam. horizontal N vertical N 4. The drawing shows a person (weight W = 572 N, L1 = 0.840 m, L2 = 0.405 m) doing push-ups. Find the normal force exerted by the floor on each hand and each foot, assuming that the person holds this position. force on each hand N force on each foot N 5. In San Francisco a very simple technique is used to turn around a cable car when it reaches the end of its route. The car rolls onto a turntable, which can rotate about a vertical axis through its center. Then, two people push perpendicularly on the car, one at each end, as shown in the drawing. The turntable is rotated one-half of a revolution to turn the car around. If the length of the car is 7.80 m and each person pushes with a 165-N force, what is the magnitude of the net torque applied to the car? N • m,As I mentinoed before, the assignment is attached as a file. There are some values, which are not given in the text, but only in the picture. So please, use the attachement. Thanks
