A metal rod of length 67 cm and mass 1.52 kg has a uniform cross-sectional area of 6.6 cm2. Due to a nonuniform density, the center of mass of the rod is 17.6 cm from the right end of the rod. The rod is suspended in a horizontal position in water by ropes attached to both ends (the figure). (a) What is the tension in the rope closer to the center of mass? (b) What is the tension in the rope farther from the center of mass? (Hint: The buoyancy force on the rod effectively acts at the rod's center.) (a) Number i (b) Number i Units Units < <

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?

A host pours the remnants of several of wine into a jug a party. The host then inserts a cork with a 2.00-cm diameter into the bottle, placing it in direct contact with the wine. The host is amazed when the host pounds the cork into place and the bottom of the jug (with a 14.0-cm diameter) breaks away. Calculate the extra force exerted against the bottom if he pounded the cork with a 120-N force.

Scurrilous con artists have been known to represent gold-plated tungsten ingots as pure gold and sell them at prices much below gold value but high above the cost of tungsten. With what accuracy must you be able to measure the mass of such an ingot in and out of water to tell that it is almost pure tungsten rather than pure gold?

(b) What is the tension in the rope farther from the center of mass? (Hint: The buoyancy force on the rod effectively acts at the rod's center.)
An object with height h,mass M, and a uniform cross-sectional area A floats upright in a liquidwith density r. (a) Calculate the vertical distance from the surface of theliquid to the bottom of the floating object at equilibrium. (b) A downwardforce with magnitude F is applied to the top of the object. At thenew equilibrium position, how much farther below the surface of the liquidis the bottom of the object than it was in part (a)? (Assume that someof the object remains above the surface of the liquid.) (c) Your resultin part (b) shows that if the force is suddenly removed, the object willoscillate up and down in SHM. Calculate the period of this motion interms of the density r of the liquid, the mass M, and the cross-sectionalarea A of the object. You can ignore the damping due to fluid friction
