1. Draw the kinematic diagram of the following mechanism. Find number of links, number of joints and label each one of them. What kind of joints are those? Write the equation for degree of freedom and compute the mobility of the mechanism. Y B D 4 6 02 A 2. As shown in the figure of offset slider-crank mechanism, the crank (link 2) is making an angle 40 with the horizontal axis. Determine the linear displacements of the slider as the crank is rotated from its current position 30 clockwise. Crank length = 2 in and connecting rod length = 6 in, offset = 1.5 in. + bin offset 1. Sin 3. For the same mechanism at this instant what the velocity of the slider if the crank is rotating at 1000 RPM? 4. The mechanism shown in the figure (next page) is used to push boxes along a platform and to a loading area. The input link is driven by a motor, which, at the instant shown, has a velocity of 20 rad/sec and an acceleration of 400 rad/sec. Drawing the acceleration vector polygon analytically determine the instantaneous acceleration and direction of the end of the input link. [
