Answer: Pulley (wheel) turns
58.3333
c
in 5 seconds
Explanation:
Belt makes 3 revolutions in a minute.
i.e. 1225 cm .3 = 3675cm
Diameter of Pulley d= 3.5 cm
Circumference of pulley c=2.π.r=2.(227).(3.5 2)=11cm
No. of revolutions made by the pulley in 3 min = 3675 / 11
No. of revolutions made by pulley in 5 sec = ( 2675 11).( 5 180)≈9.2803
One revolution of pulley will cover=2 π c
9.2803 revolutions of pulley will cover =
9.2803.2πc=
58.3333
