A uniform horizontal pipe weighing 10 kg and 1.5 m long is used as a lever. If you need to balance two objects (one on each end), where should the fulcrum be placed? The objects weigh 25 kg and 52 kg. What is the reaction force exerted by the support on the pipe? Draw the complete diagram to describe your final answer (include the lengths).
Two weights are connectedby a very light, flexible cord that passesover an 80.0 N frictionless pulley of radius0.300 m. The pulley is a solid uniformdisk and is supported by a hookconnected to the ceiling (Fig.).What force does the ceiling exert on thehook?
A car skidded off an icy road and became stuck in deep snow at the road shoulder. Another car, of 1400 kg mass, attempted to jerk the stuck vehicle back onto the road using a 5 m steel tow cable of stiffness k = 5000 N/mm. The traction available to the rescue car prevented it from exerting any significant force on the cable. With the aid of a push from bystanders, the rescue car was able to back against the stuck car and then go forward and reach a speed of 4 km/h at the instant the cable became taut. If the cable is attached rigidly to the masses of the cars, estimate the maximum impact force that can be developed in the cable, and the resulting cable elongation. Assume that the steady state force, acting on the rope, is equal to the weight of the car.
Draw the free-body diagram of the smooth uniform bar shown in Fig. 2. The bar has a mass of 20 kg.
A shaft having length equal to 10 m and diameter equal to (50+ 01) mm is simply supported at both ends. The shatt carries four masses (150 + 01) kg, (200 + 01) kg, (250 +01) kg and (300 + 01) kg. These masses are located at a distance of 1.5m, 2.5 m, 5.5 mand 7.5 m from the left hand side support, respectively. The modulus of elasticity, E, for the material of the shaft is 200 GN/m? and mass density for the shaft material is 7500 kg/m?3. Determine critical speed of the shaft in revolutions per minute for the following two cases: 1. Effect of the mass of the shaft is neglected. 2. Effect of the mass of the shaft is considered. What is the usefulness of the answers determined in this problem?
A uniform pole of 2.5m length and 4.0kg mass is suspended horizontally fromthe side of a building where it is affixed with a hinge. It is held in place by awire that extends from the unattached end of the pole at an angle of 53 degrees andattached firmly to the wall. A 10.0kg mass is hanging from the end of the poleas well under the influence of gravity.a. Draw a picture of the situation.b. Draw a comprehensive free body diagram showing the force on the wire,the mass, the pole, and both the horizontal and vertical forces on thehinge.c. Use the hinge as the axis of rotation and balance the vertical torques anddetermine the tension in the wire.d. Use inertial dynamics to find the horizontal and vertical forces on thehinge.

The hanging mobile pictured above consists of two masses, m1 and m2, suspended from a uniform 10 cm long rod, which is in turn suspended from the ceiling at an angle of 70 as pictured above. The mass m1 is 0.02 kg, while the mass of the rod is mr = 0.01 kg. Assuming the mobile is in a state of static equilibrium, find the value of mass m2.
