Pivoted rod on car
A uniform thin rod of length L and mass M is pivoted at one end. The pivot is attached to the top of a car accelerating at rate A, as shown. θ A
(a) What is the equilibrium value of the angle θ between the rod and the top of the car?
(b) Suppose that the rod is displaced a small angle φ from equilibrium. What is its motion for small φ?
Derive expressions for the critical Rayleigh numbers associated with the cylindrical and spherical geometries, Rac,crit and Ras,crit, respectively, below which keff is minimized.
A 5-kg uniform square plate is supported by two identical 1.5-kg uniform slender rods AD and BE and is released from rest in the position θ = 45°. Knowing that the angular velocity of AD as it passes through the vertical position is 5.2 rad/s, det..
You are assigned to design a heating system for a swimming pool that is 2 m deep, 20 m long and 20 m wide. The client desires that the heating system be large enough to raise the water temperature from 2 C to 3C in 2 hours. The rate of heat loss from..
A rigid vessel contains superheated water at 200 psia and 500 f. the vessel is cooled until the temperature is 200 f. determine the final pressure, specific volume, quality of the water. Draw the t-v diagram for the process.
the steady-state creep rates at 473 k for any alloy are 2.510-3 h-1 at 55 mpa and 2.410-2 h-1 at 69 mpa. the activation
A 1.00-kg beaker containing 2.00 kg of oil (density = 916.0 kg/m3) rests on a scale. A 2.00-kg block of iron is suspended from a spring scale and completely submerged in the oil as in Figure P14.63. Determine the equilibrium readings of both scale..
