1. The problem statement, all variables and given/known data The body is formed of slender rod and rotates about a fixed axis through point O with the indicated angular properties. If ω = 4.6 rad/s and α = 4.4 rad/s2, determine the instantaneous velocity and acceleration of point A. I have attached an image of the question 2. Relevant equations v = wXr a = αXr + wX(wXr) 3. The attempt at a solution r = <0.5sin(24)i + 0.23cos(24)i +0.5cos(24)j - 0.23sin(24)j> r = <0.4135i + 0.3632j + 0k> w = 4.6k va = <0i + 0j + 4.6k> X <0.4135i + 0.3632j + 0k> VA = 1.6707i + 1.9021j But it says this is wrong. What am I missing? I know for the second part that I need to use: aA = αXr + wX(wXr) but I can't seem to get wXr right. Any advice would be greatly appreciated.
