Question

Using the following data for the above diagram find Torque atO2,and forces at O2, A and B, alsocalculate shaking force and shaking torque. Consider thecoefficient of friction µ between slider and ground to be0.15.

Lengths in m, angles in degrees, angular velocity in rad/sec,angular acceleration in rad/sec2, mass in kg, moment ofinertia in kg-m2, torque in N-m and forces in N

Giving 2 =25

Use the normal convention for each of the unit and the position.Consider only the open case.

(Hints: first find different angles, angular velocities, angularaccelerations, develop equation like (11.10g), use matrixcalculation and finally compare your results with Sliderprogram).

Explanation / Answer

Lengths in m, angles in degrees, angular velocity in rad/sec, angular acceleration
in rad/sec2, mass in kg, moment of inertia in kg-m2, torque in N-m and forces in N
