#### Explanation:

Torque can be expressed by the equation:

#tau=vecF*r*sinphi# Where

#vecF# is the magnitude of the applied force,#r# is the distance from the point of application to the pivot, and#phi# is the angle between the force and radius vectors.

We are given

#vecF=vecF_G=mg=(90kg)(9.8m/s^2)=882N#

We assume an angle

#=(882N)(2m)(1)#

#=1764 Nm#
