The discussion centers on calculating torque while digging, specifically using the formula τ = F × d, where τ represents torque, F is the force applied, and d is the length of the arm or link. Participants emphasize the importance of understanding the parameters involved, such as the friction force between the digging tool and the material being excavated. A practical approach suggested includes equating the torque applied by the user at the shovel's head with the torque due to gravity acting on the shovel.

The Attempt at a Solution
tau= Fxd, where d is the length of the link. I can't go any further[/QUOTE
If right-handed you could assume the pivot point is the right hand, the torque is applied where the left hand holds the shovel, then equate that torque with the torque applied by gravity at the shovel's head.
