The plain bearing given in the figure below is placed on the floor with two 4.8 quality M16 fastened with bolts. When the system is assembled, the bolts are extended by 2 mm and the workpieces by 1 mm detected. When the system is started, 10 kN operating force acts. a) Can the bolts carry this system safely? b) Tighten these bolts with a 15 cm wrench to give the specified pre-tension force are you? Take the factor of safety as 2.5. For surfaces, take the coefficient of friction as 0.15. kc=5000N/mm; kp=10000N/mm Maximum allowable force is 1000 N

Symmetrical shoes will not create moment around the joint The position of the pads with an angle of 90° on the brake where it is placed in the figure is shown in the figure. The brake mechanism is fixed to the ground by the support plate. The disc in the figure rotates clockwise and the friction coefficient of the pads is accepted as 0.491. If a force of 565 N is applied on the arm from the point shown on the figure;a) What is the dimension e shown in the figure so that the shoe does not create a moment around the joint?how much should it be? Calculate.b) Draw free body diagrams of ABC opening lever and both lining levers.c) What is the normal force acting on each pad? How much braking torqueoccurs? calculate
An automatic door lock system is to be designed for automatically locking/unlocking car doors. The design will utilize an electric solenoid with sufficient force and stroke to provide the necessary motion. If the force required to drive the lock linkage is 9.5 N, determine if the solenoid with the following specifications meets this requirement: Number of turns Current Air gap Plunger dia, 2500 1.0 Amps 10 mm 18 mm The initial force available from a solenoid F P=2(ND)² HA 82

Required information For a bolted assembly with six bolts, the stiffness of each bolt is kb 2 Mibf/in and the stiffness of the members is km = 13 Mlbf/in per bolt. An external load of 80 kips is applied to the entire joint. Assume the load is equally distributed to all the bolts. It has been determined to use 1/2 in-13 UNC grade 8 bolts with rolled threads. It is desired to find the range of torque that a mechanic could apply to initially preload the bolts without expecting failure once the joint is loaded. Assume a torque coefficient of K = 0.2. NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. Determine the maximum bolt preload that can be applied without exceeding the proof strength of the bolts once the load is applied. The maximum bolt preload that can be applied is Ibf.
