A stepladder has negligible weight and is constructed as shown. The horizontal bar connecting the two legs of the ladder is pivoted half way up the ladder. A 47kg painter stands on the ladder a distance 4m from the foot of the ladder. The length of the ladder is 6.6m and the legs of the ladder are 8m apart on the floor.
a) find the tension in the horizontal bar. The acceleration of gravity is 9.8m/s^2. Assume the floor is frictionless and that the ladder is symmetric and forms an isosceles triangle. Treat each half of the ladder separately.
b) find the normal force on the left hand leg of the ladder and right hand leg of the ladder
c) find the magnitude of the x and y component of the reaction force at the hinge that the left half of the ladder exerts on the right half.
