#m<=350.11 " "kg#

enter image source here

#T>=m*g*sin alpha+u_k*m*g cos alpha#

#T=3200N#

#U_k=3/5#

#alpha=pi/8#

#T>=m(g*sin alpha +u_k*g*cos alpha)#

#m<=T/(g*sin alpha +u_k*g*cos alpha)#

#m<=3200/(g(sin alpha+u_k cos alpha)#

#m<=3200/(g(0.38+0.6*0.92))#

#m<=3200/(9.14)#

#m<=350.11 " "kg#
