Problem 2 Crank AB has a constant clockwise angular velocity of 2000 rpm. For the crank position shown, find the instantaneous angular acceleration of the connecting rod BD, and the acceleration of piston D. I=8in. n. 40°
The "quick-return" mechanism consists of a crank AB, slider block B, and slotted link CD. If the crank has the angular motion shown, determine the angular motionof the slotted link at this instant. (Answer Wcd = 0.866rad/s, Acd = 3.23 rad/s2)Wab= 3 rad/sαab= 9 rad/s2θ = 30o

The bell crank lever mechanism as shown in the figure is part of a lifting machine. Effort and load forces are applying though points A and D respectively. ABCD lever mechanism is a rigid body and free to rotate around pin O (over ABCD plane). As a result of a strength analysis, it has been identified two critical sections B and C as shown in the figure. If the principal stresses of a critical element at section C is as...
