1. AN ELECTRIC MOTOR ACCELERATES THE 6-in DIAMETER GRINDING WHEEL AT A RATE 0F 150 rad/s2 FROM REST UNTIL IT REACHES ITS OPERATING SPEED OF 3600 rpm. DETERMINE:
a) The time in seconds required for the wheel to reach 3600rpm
b) The number of revolutions of the wheel required to reach 3600rpm
c) The velocity in ft/s of particle P on the periphery of the wheel at 3600rpm
d) The magnitude of the acceleration in ft/s2 of this particle at 3600 rpm
e) The relative velocity VP/Q
2. ROD BC IS PINNED TO THE 10-lb SLIDING BLOCK AT POINT C AND TO ROD AB AT POINT B. IF ROD BC IS MADE TO ROTATE AT A CONSTANT RATE OF 2rpm CLOCKWISE, DETERMINE FOR THIS INSTANT:
a) The velocity in ft/s of the block
b) The angular velocity in rad/s of rod AB
c) The speed in ft/s of pin B
d) The magnitude of the acceleration in ft/s2 of pin B
e) The Instantaneous Center of rod AB is at D, YES or'NO
