Q.1

A motor’s shaft is spinning at a speed of 3000 r/min. What
is the shaft speed in radians per second?

Q.2

A flywheel with a moment of inertia of 2 kg ⋅m^2
is initially at rest. If a torque of 5 N ⋅m counterclockwise is suddenly
applied to the flywheel, what will be the speed of the flywheel after 5 s?

Q.3

A motor is supplying 60 N ⋅m of torque to its load. If the
motor’s shaft is turning at 1800 r/min, what
is the mechanical power supplied to the
load in watts? In horsepower?

Q.4

If you have mechanical power in watts is 11,310 w. what will
be power in horsepower?

Q.5

A wire of length 1m which is carrying 5.0 A in the presence
of a magnetic field 0.25T at right angle . Calculate the magnitude and direction of the
force induced on the wire.
