KE of a bar rotating at an angle- please help! 1. The problem statement, all variables and given/known data A slender prismatic bar DE Of length l(=1 m) and weight W(= 89 N) is rigidly attached at it's midpoint C to a shaft AB and makes an angle (alpha(=45degrees)) as shown in the figure. Find the kinetic energy T of the bar if it rotates with constant angular velocity (omega(=200 rpm)) about AB. 2. Relevant equations Work done= change in KE and Work done= integration of moments about the axis of rotation 3. The attempt at a solution I'm supposed to use the work- energy relation to solve this question but am clueless as to how to go about it..... please help!!
