The board sandwiched between two other boards in Figure P4.77 weighs 95.5 N. If the coefficient of friction between the boards is 0.663, what must be the magnitude of the compression forces (assumed to be horizontal) acting on both sides of the center board to keep it from slipping?
In order to get his car out of the mud, a man ties one end of a rope to the front bumper and the other end to a tree 15 m away, as shown below. He then pulls on the center of the rope with a force of 400 N, which causes its center to be displaced 0.30 m, as shown. What is the force of the rope on the car?
Two people, let’s call them person A and person B, carry a uniform board of length 6 meters and weight 150 N. Person A is 1 m from one end and person B is 2 m from the other end. What weight does person A support? What weight does person B support?
A large airplane typically has three sets of wheels: one at the front and two farther back, one on each side under the wings. Consider the Boeing 787 "Dreamliner", with a mass of 198000 kg. In this particular model, the distance from the front wheels to the rear set of wheels is 23.8 m. a) If the center of mass of the airplane is along a line through the center and 3.00 m in front of the rear wheels, how much force, in meganewtons, does the ground exert on each set of rear wheels when the plane is at rest on the runway? b) How much force, in meganewtons, does the ground exert on the front set of wheels?
A 4 m long horizontal uniform beam of mass 24 kg is supported by a wire as shown in the figure. The wire makes an angle of 26 degrees with the beam. Attached to the beam 1.6 m from the wall is a ball with a mass of 57 kg. VWhat is the tension in the string?
The drawing below shows a person whose weight is W = 603 N doing push-ups. Assume L1 = 0.880 m and L2 = 0.435 m. Calculate the normal force exerted by the floor on each hand, assuming that the person holds this position.
An auto magazine reports that a certain sports car has 53% of its weight on the front wheels and 47% on its rear wheels. (That is, the total normal forces on the front and rear wheels are 0.53w and 0.47w, respectively, where w is the car’s weight). The distance between the axles is 2.46 m. How far in front of the rear axle is the car’s center of gravity?
The arm of a crane at a construction site is18.0 m long, and it makes an angle of 15.3with the horizontal. Assume that the maximum load the crane can handle is limited by the amount of torque the load producesaround the base of the arm. What maximum torque can the crane with-stand if the maximum load the crane can handle is 607 N?
