A man of mass 40 kg is at rest between the walls as shown in the figure. If `mu` between the man and the walls is 0.8, find the normal reactions exerted by the walls on the man.

Text Solution

Verified by Experts

Since, man is at rest

`N_(1)-N_(2)=0`
`therefore N_(1) = N_(2) = N` (say)
`therefore 2mu N = mg`
`=2 xx 0.8 xx N = 400`
`therefore N = 250 N`
