- UseM = 3(N −1) − 2Jto calculate the mobility of the crank-slider mechanismthe radius of each pulley is 5 inches and the coeffiecent of friction is 0.3 a) determine the largest torque that can be transmitted if the allowable belt tension is 1000 lbs? b) what would be the largest torque if the belt is a v-belt with a groove angle of 75 degrees? c) which style belt transmits the highest torque a flat belt or a v belt?A plant is 10m ong is placed on a horizonta positin wth ts two ends resting on to inclined planed. Angle of friction on all surfaces is 20 degrees. 1. VAlue of x when plank will start to the side? 2. if P=100kn what is the reaction of A? 3. if P=100kn what is the reaction of B?
- What should be the value of the angle ? in fig. so that the motion of the 90N block impends down the plane? The coefficient of friction ? for all the surfaces is 1/3.A soft surface cone clutch must handle 1865 In-1b of torque at 1250 rpm. The large diameter of the clu is 13.75 in. and the included angle in 12.5°. The face width of the bearing surfaces is 2.5 in. Using efficient of friction 0.20. determine (a) the force (F) to engage the clutch, (b) the required normal unit pa sure on the contact surfaces when operation is at capacity Ans. 428 lb. 13.15 psia 700 kg piston initially held in place by a renewable latch above a vertical cylinder
- show free body diagamRight answer plz.otherwise don't attempt. A lift system is provided with cushion springs at the bottom of lift. The lift is free to fall. Springs are set in parallel. Specify the required number of springs, if the lift has free fall of 1.5 m from rest. Weight of lift = 30 kN Allowable deflection per spring = 370 mm Number of active turns = 15 Spring mean coil diameter = 30 mm Spring wire diameter = 30 mm Modulus of rigidity for spring = 80 GPa.Determine diameter of hand-wheel or length of handle, assuming that maximum force exerted by a man is 150 lbf. The bolt is 1" OD, 0.9" ID. Coefficient of friction is .15 You need to push down with a force of 6000lbf. This is for a handle of a screw press. Please explain the equation and I will upvote
- Torque required for achieving the tighting forceAssume 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?How many Frames multi-force member(s) have?
