Question

QUESTION 1 A slider crank linkage is shown in figure 3 below. The angular velocity and the angular acceleration of the crank are 10 rad/s and 40 rad/s2 respectively. Link AB is 50 mm and link BC is 95 mm. A point D on link BC is 0.2 times BC from point B Determine the following; 1.1 velocity of the piston, 1.2 angular velocity of links BC 1.3 acceleration of the piston 1.4 angular acceleration of link BC 1.5 acceleration of point D on link BC. 45 40 radis 10 rad/s 70°
