Question

Weight =100N

Find tension in the string (T) and normal reaction of surface (N) on the man in equilibrium. Given that T is at an angle of α = 40° with horizontal and T and N are perpendicular to each other

Answer 1

Given T = Tension N = normal reaction Perpendicular to i = inclined to plane N = mg cos alpha T = mg sin alpha } Answer alpha = 40 degree N = mg. cos 40 degree = 0.77 mg N = 0.77 mg Tension in string T = mg sin 40 T = mg [0.64] T = [0.64] mg Answer T = 0.64 mg N = 0.77 mg m = mass of man
