The Crank AB Turns Uniformly At 180 rpm. In The Clockwise Direction & The Blocks At D & E Are Working In Frictionless Guides. Draw The Velocity Diagram For The Mechanism & Find The Velocities Of The Sliders D & E In Their Guides. Also Determine The Turning Moment At A If a Force Of 500N. Acts On D In The Direction Of Arrow X & a Force Of 750N. On E In The Direction Of Arrow Y.

Given: $N_{BA}$ = 180 rpm. or $\omega_{BA}$ = $2\pi\times\frac{180}{60}=18.85$ rad/s

Since AB= 0.45m, therefore velocity of B with respect to A or velocity of B (because A is a fixed point)

$v_{BA}=v_{B}=\omega_{BA}\times AB=18.85\times 0.45=8.5 m/s$

Velocities of the sliders D and E

First of all the space diagram …
