while considering torque acting on any object for eg say a ladder is it necessary to take torque only about free end like the one in contact with the floor or the wall cant we take the torque about centre of mass?
|
if u think u can,u can if think you can't you're right |

no its not necessary, you can take torque about any point, but generally preference is made for the point which minimises the calculations,

GENERALLY WE CALCULATE TORQUE ABOUT A POINT THRU WHICH MAX. FORCES ACT SO THAT THE EFFECT OF FORCES GET CANCELLED.
