Shown below is a power hacksaw. At this instant, the electric motor rotates counterclockwise and drives the free end of the motor crank (point B) at a velocity of 12 in./s. Additionally, the crank is accelerating at a rate of 37 rad/s2. 15° 6" В 30° 1.75" (a) a. Draw the mechanism to scale. b. Draw the Velocity Polygon. Use Appropriate scale. Find the Relative Velocity of C with respect to B. С.

For the following mechanism, if the length of rod AB, I = 2.0 m, and its angular velocity w = 5.5 rad/s, determine the magnitude of the angular velocity of rod AB. Please pay attention: the numbers may change since they are randomized. Your answer must include 2 places after the decimal point and proper unit. 0.5 m B 30° A 45° Your Answer: Answer units
