16) In the figure, a 10.0-m long bar is attached by a frictionless hinge to a wall and held horizontal by a rope that makes an angle 0 of 53° with the bar. The bar is uniform and weighs 39.9 N. How far from the hinge should a 10.0-kg mass be suspend ed for the tension T in the rope to be 125 N? 10 kg 10 m ctin

A uniform bar 7.5 m long is held against a rough wall by a light rope as shown in the diagram. The pulley may be assumed to be frictionless, W = 140 N and the weight of the bar is w = 40 N. Find (a) the tension in the rope attached to the bar, and (b) the minimum coefficient of friction between the bar and the wall if the bar does not slip. There is no hinge connecting the...

A 45.0 kg uniform rod 4.40 m long is attached to a wall with a hinge at one end. The rod is held in a horizontal position by a wire attached to its other end. The wire makes an angle of 30.0 ∘ with the horizontal, and is bolted to the wall directly above the hinge. If the wire can withstand a maximum tension of 1300 N before breaking, how far from the wall can a 70.0 kg person sit...

A hungry bear weighing 750 N walks out on a beam in an attempt to retrieve a basket of food hanging at the end of the beam. The beam is uniform, weighs 100 N, and is 8.00 m long; the basket weighs 150.0 N. (a) when the bear is at x = 3.00 m, find the tension in the wire and the components of the force exerted by the wall on the left end of the beam, (b) At this...

A 1.50-m-long metal bar is pulled to the right at a steady 4.0 m/s perpendicular to a uniform
A 1.50-m-long metal bar is pulled to the right at a steady 4.0 m/s perpendicular to a uniform, 0.5T magnetic field. The bar rides on parallel metal rails connected through R = 24.0Ω, as shown in the figure below, so the apparatus makes a complete circuit. You can ignore the resistance of the bar and the rails. a) (5.0 pts) Calculate the magnitude of the emf induced in the circuit. b) (5.0 pts) Find the direction of the current induced in the...

48. A hungry bear weighing 700 N walks out on a beam in an attempt to retrieve a basket of food hanging at the end of the beam (Fig. P12.43). The beam is uniform, weighs 200 N, and is 6.00 m long: the busket weighs 80.0 N. (a) Draw a free-body diagram for the beam. (b) When the bear is at x - 1.00 m, find the tension in the wire and the components of the force exerted by the...

A beam is attached to a vertical wall with a hinge. The mass of the beam is 1800 kg and it is 4 m long. A steel support wire is tied from the end of the beam to the wall, making an angle of 30° with the beam (see the figure below). 1)Calculate the tension in the support wire. Assume the beam has a uniform density. kN 2)What is the vertical component of the force exerted by the hinge on...
