Unformatted text preview: Machine Design I (ME-4133) Test I Attempt all 21 questions, 5% each, and accumulate up to 105% Time 80 minutes Justify your answers with the applicable equation, or with a short sentence or two All figures are drawn to their actual dimensions Student Name: __________________________ SSN: ___________________ 1. Disk 2 with center O rotates with angular velocity 2 as shown in Figure. What is the angular velocity of link 3? rad/s 2 2 = 2 1 1 3 O rad/s 2 2 = 2 1 1 rad/s 2 2 = 2 1 1 3 O rad/s 3 = 2. Disk 2 roles on the ground with no slip. The velocity of its center A is shown in the Figure. Draw on the Figure below the velocity of B with the correct amplitude and direction. A B 1 2 in./s 1 = A v A B 1 2 in./s 1 = A v 3. Slider A moves with velocity as shown in the figure. What is the angular velocity A v 2 of link 2? 1 1 2 3 in./s 10 = A v A 1 1 2 3 in./s 10 = A v A rad/s 2 = 4. The figure shows a rigid body with three points A , B , C , attached to it. The velocity of A and B are and , respectively. Draw on the figure the velocity of C in its correct magnitude and direction....
