Problem 1 (20 pts): Calculate the mass, center of mass and mass moment of inertia of each link (with pins), and fill in the table below. The fasteners in the link are assumed to be of the same material. Bring answers to the fourth decimal place for mass and to the eight decimal place for Moment of Inertia. Link Mass Moment of Inertia about CM Crank Coupler (including rider) Rocker Problem 2 (40 pts): Conduct a position/velocity/acceleration analysis of the rider. Plot the trajectory of the rider (in meters) and the x and y acceleration of the rider (in m/s2) for one rotation of the crank. Problem 3 (40 pts): Perform a force analysis on the linkage (with rider) assuming that the rider is a point mass located at the center of the coupler. Plot the torque required to spin the crank at 100 rpm versus crank angle. Using the peak torque value, how powerful should be motor be (in horsepower)?
