Question

A large tree limb with a mass of 60 kg extends out from a tree trunk as shown in the figure. If the distance from the base of the tree limb to its center of mass is 2 m, what is the torque about the base of the limb?

Group of answer choices

491 N m

692 N m

955 N m

588 N m

1,018 N m

Answer 1

we know torque = R* F(CROSS PRODUCT OF R AND F)

                      = RF SIN(THETA)

                      = 2 mg sin 60

                        = 1018Nm
