A racetrack has the shape of an inverted cone, as the drawing shows. On this surface the cars race in circles that are parallel to the ground. (a) Draw the free-body diagram showing the forces that act on the car, assuming the friction force equals zero in this case. (b) For a speed of 34.0 m/s, at what value of the distance d should a driver locate his car if he wishes to stay on a circular path without depending on friction?

To measure the static friction coefficient between a 1.6−kg block and a vertical wall, the setup shown in the drawing is used. A spring (spring constant = 510 N/m ) is attached to the block. Someone pushes on the end of the spring in a direction perpendicular to the wall until the block does not slip down. The spring is compressed by 0.039 m. (a) Draw the free-body diagram showing the forces that act on the block. (b) What is the coefficient of static friction?

A person with mass 55.0 kg stands 2.00 m away from the wall on a uniform 6.00−m beam, as shown in the figure. The mass of the beam is 40.0 kg. a) Draw a free-body diagram of the beam, similar to Figure 8.18 b. There are four forces that act on the beam. Give each force a subscript letter. b) Write an expression for Στi, the net torque on the beam around the pin on its left end, similar to the first equation on p. 238. c) For each of the four forces on the beam, what is the angle θ between the force and the position vector? (The position vector goes from the pin to where the force is applied to the beam. Also, if the position vector is zero any of the forces, give τ = 0 as your answer.) d) For each force, the torque from that force is defined as τ = r→×F→ = rFsin⁡θ. Using this definition, evaluate your answer to part b), to write an equation similar to the 2 nd equation on p. 238. e) Solve the last equation for the tension in the cable.
