The discussion revolves around calculating the torque acting on an arm while digging, specifically using the formula tau = F x d. Participants are exploring the parameters involved in this context.
The discussion is ongoing, with participants seeking clarification on the parameters and exploring different aspects of the problem. Some guidance has been offered regarding the pivot point and the relationship between the forces involved.
There is a mention of needing to consider the friction force between the sand and the tool, indicating potential constraints in the problem setup.

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.
