1. The problem statement, all variables and given/known data Here is a picture of the problem! http://imgur.com/suJxZ0F Also here it is in text, Rod AB rotates with the angular velocity and acceleration clockwise as shown. Points A,B and C are pin connected. Point C is free to slide horizontally as shown in the figure at the instant shown determine The velocity and acceleration of point B The angular velocity and acceleration of rod BC, omegaBC, alphaBC The acceleration of point C omegaAB = 6 rad/s alphaAB = 3 rad/s length of rod AB = 0.5 m length of rod BC = 0.8 m 2. Relevant equations v = ωr (1) an = ω2r (2) at = αr (3) vb = va + vb/a (4) ab = aa + ab/a (5) ωdω = αdθ (6) 3. The attempt at a solution First I found the velocity of B as 3 m/s but using equation (1) and the angular velocity and length of the rod AB. Next I determined the normal and tangential acceleration of B by using equations (2)(3) and the angular acceleration, angular velocity, and length of rod AB. From the normal and tangential acceleration I used Pythagorean theorem to find the acceleration of point B = 18.06 m/s2. Next I got the angular velocity of BC by using equation (1) and using the length of BC as well as the velocity of B = 3.75 m/s. Next I found the angular acceleration of BC by using equation 3 and the acceleration of B and the length of BC, the angular acceleration I found was 22.575 rad/s2. I don't think I am doing this right, could somebody help me?
