Question

For the stepladder shown in Fig. 12-51, sides AC and CE are each 3.34 m long and hinged at C. Bar BD is a tie-rod 0.662 m long, halfway up. A man weighing 746 N climbs 2.51 m along the ladder. Assuming that the floor is frictionless and neglecting the mass of the ladder, find (a) the tension in the tie-rod and the magnitudes of the forces on the ladder from the floor at (b) A and (c) E. (Hint: Isolate parts of the ladder in applying the equilibrium conditions.)
