Consider that a rigid body with unit vectorsb move with respect to the inertial frame ê. At the initial time, ê = b1, ê2 = b2 and êz = b3. The final orientation of b with respect to ê is given by: ū = -3ê1 – 2ê2 + êg 8 = -45° (a) Sketch ū in 3D including the direction of the rotation given by 8. %3D (b) Compute the final DCM.

Equation of Motion The triangle is made of 3 rods of a length 1-2.1ft and density is p = 4 lb/ft. ^ 1) Establish what you think is the best Coordinate system for this problem and explain why. 2) Find the location of the center of gravity (x bar and y bar). 3) Find the weight of the triangle. 4) Find the Mass Moment of Inertia at O of the triangle. 5) Draw the FBD and kinetic diagram of the triangle. 6) Find the accelerations of the triangle (angular and linear). 7) Find the Pin Reaction at O: . On and Ot • or Ox and Oy . • Magnitude O, and direction. In the box below, enter the angular acceleration & in rad/s with one decimal. Include the sign + if CCW or - sign if CW.

for the given figure , draw the 2d sketch using AutoCad and give the dimension

Hi, I have an engineering dynamics question.
