Step by step
Solved in 3 steps
- Find the equilibrium positions of the 30-lb homogeneous bar and investigate their stability.The homogeneous plate of weight W is supported by a ball-and-socket joint at D and three wires. Draw the FBD of the plate and count the unknowns.Engineering Mechanics (Equilibrium): The homogeneous 40 kg basr ABC is held by a horizontal rope attached to end C. Neglecting friction, determine the tension in the rope.
- The homogeneous 200-lb sign is suspended from three wires. Find the tension ineach wire.Q 40/A homogeneous bar of length / and weight w lb rests horizontally as shown in Fig. 40 with its free endon a block of weight W. the block W is at rest on a plane inclined at the angle a with the horizontal. Determine the necessary coefficient of friction u between the block and the plane for equilibrium. Assume no friction between the bar and the block.Equilibrium of Rigid Bodies
- What is the second condition for equilibrium? Cite two or three situations wherein this principle is applicable. State how the clockwise moment of force is related to the counterclockwise moments of force when the meterstick is in equilibriumA given mass of 23 kg is suspended from a vertical pole by means of a horizontal rod ST hinged at pt.T and a cable SR to the pole; 8m above pt.T. SHOW FBDSITUATION 1. The quarter circular plate is subjected to forces as shown. If the plate weighs 50 kg, and assuming equilibrium
- A system is being designed to lift objects with a cable. One end of the cable will be attached to the material while the other end will be permanently fixed to a drum (cylinder) so that as the drum is rotated the cable is wound around its outside surface. Two designs for a drum are being considered for use in the system. Design “A” calls for a solid aluminum pulley (paluminium = 2800 kg/m 3 ) while design “B” calls for a steel pulley (psteel = 8000 kg/m 3 ) that is hollow (it can be modeled as a 12 mm thick shell). Calculate the torque required to accelerate the pulley for Design B to reach 500 RPM in 4 seconds if the pulley is 500 mm wide. Assume constantThe external effect of the force is the same on each rigid bodyAssume that there are no frictional forces between the pulleys and the strings, and the strings are mass-less. The frictional coefficient between the1 kg and 2 kg is 0.05, the frictional coefficient between the 2 kg and 5 kg is 0.1, and the frictional coefficient between the 5 kg and the table is 0.2. (a) Draw free-body diagrams for each mass? (b) Calculate the magnitudes of normal forces and frictional forces?(c) If we release 4 kg and 3 kg from rest what are the accelerations of each mass? (System has two different accelerations)(d) Calculate the tensions in each string?
