a) The angular velocity BD at the instant BD is perpendicular to OA.
b) The angular acceleration BD at the instant BD is perpendicular to OA.

 

The image depicts a mechanical system involving levers and pulleys. Here's a detailed description: - The system includes a lever arm that pivots around a fixed point labeled O. - There is a horizontal bar connected to the pivot at O, extending to a point labeled B, which is located 75 mm away from the edge of a vertically fixed surface. - The vertical length from point B to the base of the fixed surface is specified as 250 mm. - A segment vertically connects point B to a lower point D, with a length of 100 mm. - At the pivot point O, another arm extends diagonally to the right, connecting to another point labeled A, measuring 125 mm from O. - A sector-shaped component, labeled E, is attached at point A and has a radial measure extending 200 mm to another point F. - The upper right section shows a rope or cable wrapped around a pulley, moving horizontally to the left at a velocity of 4 m/s. This diagram illustrates a mechanical linkage system, potentially demonstrating a mechanism that converts rotational motion into linear motion (or vice versa), applying geometric principles and dynamics.
