1.If OA has a constant counterclockwise angular velocity of 10rad/s, calculate the angular acceleration of link AB and link BC for the position where the cordinates of A are x=-60mm and y = 80mm. Link BC is vertical for this position.

2.Two identical squares (each18x18mm ) sit on the x axis and are joined at the y axis to form a rectangle. What is the rectangle’s product of inertia?
