For the stepladder shown in the figure, sides AC and CE are each 2.89 m long and hinged at C. Bar BD is a tie-rod 0.555 m long, halfway up. A man weighing 663 N climbs 2.17 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:...
For the stepladder shown in the figure, sides AC and CE are each 2.60 m long and hinged at C. Bar BD is a tie-rod 0.778 m long, halfway up. A man weighing 823 N climbs 1.95 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.
