At Point C On AB ,150 mm From A, The Rod CE 350 mm Long Is Attached. This Rod CE Slides In a Slot In A Trunnion At D. The End E Is connected By a Link EF, 300mm Long To The Horizontally Moving Slider F.

For The Mechanism In The Position Shown, Find

1.Velocity Of F.

2.Velocity Of Sliding Of CE In The Trunnion , And

3.Angular Velocity Of CE.

Difficulty: High

Given: $v_{AO}$ =120 rpm., or $\omega_{AO}$ = $2\pi \times\frac{120}{60} = 4\pi$ rad/s.

Since the length of crank OA =100 mm =0.1m, therefore velocity of A with respect to O or velocity of A (because O is a fixed point),

$v_{AO}$ = $v_{A}$ = $\omega_{AO}$ $\times$ OA = $2\pi \times$ 0.1 …
