shown in figure (6-E7) is µ. Find the maximum force
that the man can exert on the rope so that the board
does not slip on the floor.

Thank you Sir...
Last question answer:
T= u(M+m)g/(sin¢ + cos¢ + 1)
where u = coeff. of friction between board and floor...

Thank you bhaiya so much well explained

(M-m)gμ²/1+ cos¢-sin¢μ² is it right (μ² = μ2)

Thank you for the explanation. My answer to the last question was [ (Mg/sin@) - [(u2mgcos@)/u1sin@(cos@+1)] ] ( where @= theta) which ik is wrong cause it can never really be this complex. Can someone please help 😭
