Chapter 5, Problem 19SP
An 800-N painter stands on a uniform horizontal 100-N plank resting on the rungs of two separated stepladders. The plank is 4.00 m long, and it is supported at its very ends (not a very safe arrangement). The painter stands on the plank 1.00 m from its right end. Determine the upward force exerted by the ladder on the left. [Hint: Draw a diagram and locate the weight of the plank at its c.g. and take the torques around the right end.]

- In order to get his car out of the mud, a man ties one end of a rope to the front bumper and the other end to a tee 15 m away as shown below. He then pulls on the center of the rope with a force of 400 N, which causes its center to be displaced 0.30 m, as shown. What is the force of the rope on the car?arrow_forwardA stepladder of negligible weight is constructed as shown in Figure P10.73, with AC = BC = ℓ. A painter of mass m stands on the ladder a distance d from the bottom. Assuming the floor is frictionless, find (a) the tension in the horizontal bar DE connecting the two halves of the ladder, (b) the normal forces at A and B, and (c) the components of the reaction force at the single hinge C that the left half of the ladder exerts on the right half. Suggestion: Treat the ladder as a single object, but also treat each half of the ladder separately.

- The following figure shows a 4 m bar attached to the wall through a hinge that rotates freely, but is tied to the wall at its other end so that the system is in equilibrium. If the bar weighs 40 N and the tension in the rope is 20 N, find the angle of inclination θ (theta) that the bar makes with the x-axis and the magnitude of the reaction force at the hinge.arrow_forwardA uniform board is suspended from a ceiling and supported horizontally by two wires, A and B. The board is 2.0 m long and has a mass of 25 kg. What is the tension in each of the two wires when a sign of 35 kg is hung on the board a distance of 0.50 m from one end?arrow_forwardFrom the step ladder shown in the figure, sides AC and CE are each 2.44 m long and hinged at point C. Bar BD is a tie-rod 0.762 m long, halfway up. A man weighing 845 N climbs 1.8 m along the ladder. Assuming the floor is frictionless and neglecting the mass of the ladder, find the tension (in N) in the tie-rod.arrow_forward
- A 75 kg man's arm, including the hand, can be modeled as a 79-cm-long uniform cylinder with a mass of 3.7 kg. In raising both his arms, from hanging down to straight up, by how much does he raise his center of gravity?arrow_forwardA meter stick is pivoted at its 50cm mark but does not balance because of non-uniformities in its material that cause its center of gravity to be displaced from its geometrical center. However, when weights of 150g and 300g are placed at the 10cm and 75cm marks, respectively, balance is obtained. The weights are then interchanged, and balance is again obtained by shifting the pivot point to the 43cm mark. Find the mass of the meter stick and the location of its center of gravity.arrow_forwardA tightrope walker with a mass of 70.0kg stands balanced in the middle of a tightrope so that the rope sags 8.00° with respect to the horizontal on both the left and right sides of the midpoint.
