(A)The diagram shows an object of mass m attached to a bar of length I by a short cable. The left end of the bar is held up by a hinge, attached to the wall. The bar is maintained in its horizontalorientation by a longer cable, attached from the end of the rod to the wall. The long cable makes an angle with the bar and has tension Fr. The mass of the bar is not negligible. The cables areassumed to have uniform linear density, the hinge is assumed to be frictionless and to have negligible radius, and the mass of the bar is assumed to be uniformly distributed along the length of thebar. Students calculate the theoretical tension in the long cable and then measure the actual tension in the cable. The measured tension is more than the theoretical tension. If the measurement iscorrect, which of the following could account for the discrepancy?BCDThe radius of the hinge is not negligible.The linear density of the short cable increases vertically.The linear density of the bar decreases with distance from the wall.The rotational inertia of the bar about the hinge is less than ML².FTThe rotational inertia of the bar about the hinge is greater than ML².m

Given that:FT, measured>FT, actualAnd the measurement is correct.

(Figure 1) shows a metal advertising sign of weight w suspended from the end of a horizontal rod of negligible mass and length L. The end of the rod with the sign is supported by a cable at an angle θ from the horizontal, and the other end is supported by a hinge at point P. Using the idea that there is zero net vertical force on the rod with the attached sign, find the tension in the cable. Using the idea that there is zero net horizontal force on the rod with the attached sign, find the horizontal component of the force exerted by the hinge.
A uniform plank of wood has a mass of 19.5kg and a length of 2.0m. A person holds the plank using both hands. The first hand exerts a downward force, F⃗ , at an end of the plank.

In a city park a nonuniform wooden beam 4.00 m long is suspended horizontally by a light steel cable at each end. The cable at the left-hand end makes an angle of 30.0° with the vertical and has tension 620 N. The cable at the right-hand end of the beam makes an angle of 50.0° with the vertical.
