A hydraulic brake system consists of the brake pedal, a master cylinder, a brake cylinder, a brake shoe, and a wheel drum (see the figure below). When the driver exerts a force Fhrake on the pedal, the result is a force of friction f on the wheel drum and hence a frictional torque about the axle. The master cylinder piston's cross-sectional area Ame is 1.80 cm², while the brake cylinder piston's cross-sectional area Ap is 6.40 cm2. The coefficient of friction between the brake shoe and the drum is 0.500, and the wheel drum has a radius of 44.3 cm. Determine the frictional torque about the axle when the force exerted on the brake pedal is 41.7 N. (Give the magnitude of your answer in N• m.)

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?

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.
