The electric motor with an attached disk is running at a constant low speed of 105 rev/min in the direction shown. If the motor pivots about the x-axis at the constant rate y = 9.8 rad/sec with no rotation about the Z-axis (N = 0), determine the angular acceleration a of the rotor and disk as the position y = 30° is passed. Also find the velocity and acceleration of point A, which is on the top of the disk at this instant. OC = 16" CA = 7" Answers: a = (i i+ i j+ i k) rad/sec2 VA = (i i+ i j+ i k) in./sec aa = (i i+ j+ i k) in./sec2 ---

Describe working and environmental conditions that lead to failure for a product made from material from each of the four material categories.

Match patterns representing different materials are allowable and specified by drawing standards. True? A. Yes B. No, they may be represented at the engineering discretion   Instead of using multiple sections for different features, I can cluster them under a single section using A. An offset section B. A half section C. A Multiview section D. None of the above
