Unformatted text preview: equation r = 100(2cos ) mm. Determine the acceleration of the slider block when = 120° in rcoordinates. mm Midterm 1a ENES 221 Name:_____________________ Section______________ 2. [34 points] The wheel in the figure below rolls without slipping with constant angular velocity 6 . 1 # $ rad/s. Calculate the angular velocity of the bar AB and the velocity of the slider B when the mechanism is in the position shown. B A 0.2 30 o 1 m 0.4 $ % =1.6 rad/s Dimensions in meters Midterm 1a ENES 221 Name:_____________________ Section______________ A a # B a 2 rad/s 69 . 7 # & " 3. [34 points] Each of the sliding bars engages its respective rim of the two riveted wheels (they move as one rigid body) without slipping. The bar A accelerates to the right and there is no acceleration of bar B . The wheel has an angular acceleration magnitude of 7.69 rad/s 2 in the direction shown. Calculate the acceleration of point P at the instant depicted....
