Question 9
For the next 5 questions refer to the following problem statement:
When the slider-crank mechanism is at the position shown, link AB has an angular velocity of \(\omega_{AB} = 2.5\) rad/s, and an angular acceleration of \(\alpha_{AB} = 12\) rad/s$^2$. Assume that links AB and BC are massless and that slider C weighs 10 lbs. The system parameters are as follows: \(L_{AB} = 1.5\) ft, \(L_{BC} = 3\) ft, \(\beta = 45^\circ\), \(\theta = 45^\circ\). Note that link BC is in horizontal position.
