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: Isolate parts of the ladder in applying the equilibrium conditions.)
Here we apply concept of static equilibrium and apply condition for static equilibrium.

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.

Please be as detailed as you can be 8. Stepladder. In the stepladde long. The tie-rod BD of length 1-3.00 ft is half way up. A person weighing W = 195 lbs climbs d = 7.00 ft along the ladder side AC, as shown. Assume the floor is frictionless and neglect the weight of the ladder. Find (a) the tension T in the tie-rod and (b) the forces exerted on the ladder by the floor. ure , both
9. A stepladder consists of two halves, hinged at the top, and connected by a tie rod which keeps the two halves from spreading apart. In this particular instance, the two halves are 2.50 m long, the tie rod is connected to the center of each half andi is 70.0 cm long. An 800-N person stands 3/5 of the way up the stepladder and another one of same weight stands 1/10 of the way, as shown in the figure. Neglecting...
A student is standing on a ladder as shown in the figure to the right. Each leg of the ladder is 2.6 m long and is hidged at point C. The tie-rod (BD) attached halfway up and is 0.7 m long. The student is standing at a spot 1.95 m along the leg and her weight is 541 N. (You may ignore the weight of the ladder and any minor friction between the floor and the legs.) 1) What is...
A uniform ladder 12 meters long rests against a vertical frictionless wall, as shown in the figure. The ladder weighs 400 N and makes an angle θ = 51° with the floor. A man weighing 874 N climbs slowly up the ladder. When he is 78 m from the bottom of the ladder, it just starts to slip. What is the coefficient of static friction between the floor and the ladder? 7.8 m
