Question

Tom and Jerry both push on the 3.20m -diameter merry-go-round shown in the figure

part a. If Tom pushes with a force of 39.7N and Jerry pushes with a force of 35.7N , what is the net torque on the merry-go-round?

part b.What is the net torque if Jerry reverses the direction that he pushes by 180? without changing the magnitude of his force?

Explanation / Answer

Force exerted by Tom is Ft = 39.7 N

Force exerted by J is Fj = 35.7 N

The torque applied by Tom is

Tt = R*Ftsin?

?t = 1.6 m * 39.7 N * sin60

?t = 55.009 Nm

The torque applied by Jerry is

?j = R*Fjsin?

?j = 1.6 m * 35.7 N * sin80

?j = 56.252 Nm

a)

The net torque actig on the wheel is ? = ?j - ?t

? = 1.243 Nm

b)

When J reverses the direction

? = ?j + ?t

? = 111.261 Nm
