Homework Statement
In the mechanism shown below, the angular velocity of link 2 is 17 rad/s CW, constant. Find the angular velocity (magnitude and direction) of link 3. The distance between A and C is 109 mm, the length of link 3 is 125 mm, and θ= 111°. Note: B is a pin-slider
In the mechanism shown above, find the relative velocity (magnitude) of point B with regards to link 2.
In the mechanism shown above, find the direction of the relative velocity of point B with regards to link 2. Take the right-hand direction as a reference axis and CCW positive.
In the mechanism shown above, determine the angular acceleration (magnitude and direction) of link 3.
Homework Equations
a3 = a3t + a3n + a rel + a cor
a3t = αr
a3n = ω^2r
a cor = 2ωv
The Attempt at a Solution
So I have done the first 3 parts of the question correctly getting
-7.853rad/s = wab
0.800m/s = Vb
-291deg
I am not sure how to get the acceleration though. I'm not sure how to find the tangential component and the relative acceleration.
Thanks
