Problem 1: The figure below shows a safe of mass M = 450 kg hanging by a negligible mass rope hanging from a frame that consists of a uniform hinged beam (m = 80 kg) and a horizontal cable of negligible mass. The frame has a side a = 2.0 m and a sideb of unknown value. The reaction force at the hinge has a magnitude of R = 7810 N (pointing up and to the right). Find the value of the length of side b. You must solve this problem by using the concepts of equilibrium covered in chapter 11. Do not use trigonometry or the value of the angle e to find the value of b. Cable Beam com Rope Hinge M

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.
A rigid vertical rod of mass 75 kg and length 4.0 m is connected to the floor by a bolt through its lower end A. The rod also has a wire connected between its top end B and the floor as shown in the figure. A horizontal force F = 500 N is applied at the midpoint of the rod. What is the tension in the wire?
a 50.0 kg uniform square sign, of edge length L=2.00m, is hung from a horizontal rod of length dh = 3.00 m and negligible mass.

What are the (b) magnitude and (c) direction (left or right) of the horizontal component of the force on the rod from the wall, and the (d) magnitude and (e) direction (up or down) of the vertical component of this force?
A uniform plank of length 5.0 m and weight 225 N rests horizontally on two supports, with 1.1m of the plank hanging over the right support. To what distance x can a person who weighs 377 N walk on the overhanging part of the plank before it just begins to tip?
A spade is modelled as a uniform rod, of mass 2kg and length 90cm, attached to a uniform square lamina, of side 20cm and mass 0.5kg. A gardener holds the spade horizontally with hands 30cm and 60cm from the end of the rod. Find the vertical forces exerted by the gardener's hands. Im stuck on this q, pls help.
a nonuniform bar is suspended at rest in a horizontal position by two massless cords. One cord makes the angle u=36.9° with the vertical; the other makes the angle f =53.1° with the vertical. If the length L of the bar is 6.10 m, compute the distance x from the left end of the bar to its center of mass.
A 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. Figure P10.73 Problems 73 and 74.

The hanging mobile pictured above consists of two masses, m1 and m2, suspended from a uniform 10 cm long rod, which is in turn suspended from the ceiling at an angle of 70 degrees as pictured above. The mass m1 is 0.02 kg, while the mass of the rod is mr = 0.01 kg. Assuming the mobile is in a state of static equilibrium, find the value of mass m2.
A uniform horizontal beam 5.00 m long and weighting 3.03 102 N is attached to a wall by a pin connection that allows the beam to rotate. Its far end is supported by a cable that makes an angle of 53.0° with the horizontal (Figure (a)). If a person weighing 6.05 102 N stands 1.60 m from the wall, find the magnitude of the tension in the cable and the force exerted by the wall on the beam. T = N Rx = N Ry = N Even if we selected some other axis for the torque equation, the solution would be the same. For example, if the axis were to pass through the center of gravity of the beam, the torque equation would involve both T and Ry. Together with Equations (1) and (2), however, the unknowns could still be found—a good exercise. In this example, notice the steps of the Problem-Solving Strategy could be carried out in the explicit recommended order.QUESTION What happens to the tension in the cable if the man in Figure (a) moves farther away from the wall? The tension would…
