Figure 1 shows a computer monitor sitting on a desk and the desk rests on the surface of the earth.

A 20-cm-long wrench is used to tighten a nut. The wrench handle is pulled at 35° from the perpendicular of the handle with a force of 60 N. How much torque is exerted on the nut?

In 2014, the Rosetta space probe reached the comet Churyumov– Gerasimenko. Although the comet’s core is actually far from spherical, in this problem we’ll model it as a sphere with a mass of 1.0 x 1013 kg and a radius of 1.6 km. If a rock were dropped from a height of 1.0 m above the comet’s surface, how long would it take to hit the surface?

A meter stick balances horizontally on a knife-edge at the 50.0 cm mark. With two 5.04 g coins stacked over the 18.2 cm mark, the stick is found to balance at the 41.8 cm mark. What is the mass of the meter stick? Number i Units

PW-3 An elevator motor is capable of lifting a 2,500kg elevator 50.0m with a constant speed in 12.0 seconds. a) Apply Fet ma to find the force needed to lift the elevator. b) Find the power of the elevator motor in watts and in horsepower. (1H.P.-750W) c) If the power of the elevator motor is 200H.P., find the constant speed at which the 2,500kg elevator can be raised. d) If the power of the elevator motor is 200H.P., find the constant speed at which the elevator can be raised if the elevator and its contents have a mass of 4,000kg

The fishing pole in the figure below makes an angle of 20.0° with the horizontal. What is the torque exerted by the fish about an axis perpendicular to the page and passing through the angler's hand if the fish pulls on the fishing line with a force F with arrow = 90 N at an angle 37.0° below the horizontal? The force is applied at a point L = 2.20 m from the angler's hands.

Jackson finds an old well with a rope, bucket, a shaft that spools the rope, and a large crank wheel that turns the shaft to bring up the bucket of water. The bucket and the water have a total mass of 10.33kg, the shaft has a diameter of 15cm, and the crank wheel has a radius of 0.625m. Ignoring the mass of the rope, use torque to find the tangential force on the crank wheel required to lift the bucket and the water at a constanst speed.

A planet rotates through one complete revolution every 27 hours. Since the axis of rotation is perpendicular to the equator, you can think of a person standing on the equator as standing on the edge of a disc that is rotating through one complete revolution every 27 hours. Find the angular velocity of a person standing on the equator

A gymnast with a mass of 54 kg stands on the end of a uniform balance beam as shown in the figure.  The beam is 5.50 m long and has a mass of 250 kg.  Each support is 0.54m from the end of the beam.  What is the force on the beam due to support 2?
