4 In the mechanism shown, the centre of mass of link 3 is at G3, which is located at the centre of link 3. The mass of link 3 is 0.5 kg. Its moment of inertia about G; is 0.0012 N-s2-m. The weights and moments Of inertia of members 2 and 4 may be neglected. Link 2 is driven at a constant angular velocity of 50 rad/s CW by the torque applied to link 2. The mechanism moves in the...

A 60-mm diameter solid 1030 cold-drawn and machined steel shaft is mounted on anti-friction roller bearings modeled as simple supports and carries two pulleys with belts wrapped B = 150° at a constant, non-critical speed. The shaft has the yield, ultimate and endurance limit strengths of 1030 cold-drawn steel. It is required that the shaft has infinite fatigue life. It is also required that deflection not exceed 1.5 mm at any point and that the maximum angle of twist not...

3. An experiment is set up as shown in Figure Q3 to measure the moment of inertia of a circular flywheel. The mass of 30 kg is attached to a light inextensible string which is wrapped around the outer diameter of the flywheel which has a radius of 0.4 m. The mass is released when the system is at rest and drops 5.4 m in a time of 3 seconds. Friction in the bearings can be neglected Flywheel Bearing 30...

1. A block with weight W = 30 N is on a flat horizontal surface. You pull to the right with a force F = 16 N. There is gravity present and the coefficient of friction is static = 0.4 and kinetic - 0.25. You are also pulling straight up with an applied force of 12 N. Now what are: The normal force N-_ the frictional force f- the net force on the block Foot and acceleration a = 2....

INVESTIGATION 10 ROTATIONAL MOTION OBJECTIVE To determine the moment of inertia I of a heavy composite disk by plotting measured values of torque versus angular acceleration. THEORY Newton's second law states that for translational motion (motion in a straight line) an unbalanced force on an object results in an acceleration which is proportional to the mass of the object. This means that the heavier...
