The flywheel of a steam engine runs with a constant angular velocity of 180 rev/min. When steam is shut off, the friction of the bearings and of the air stops the wheel in 1.1 h. (a) What is the constant angular acceleration, in revolutions per minute-squared, of the wheel during the slowdown? (b) How many revolutions does the wheel make before stopping? (c) At the instant the flywheel is turning at 90.0 rev/min, what is the tangential component of the...

The flywheel of a steam engine runs with a constant angular velocity of 140 rev/min. When steam is shut off, the friction of the bearings and of the air stops the wheel in 2.6 h. (a) What is the constant angular acceleration, in revolutions per minute-squared, of the wheel during the slowdown? (b) How many revolutions does the wheel make before stopping? (c) At the instant the flywheel is turning at 70.0 rev/min, what is the tangential component of the...

An airplane is flying at a constant horizontal velocity of 184.5 m/s and drops a rocket. The rocket falls for 10.24 s without air resistance and under the influence of gravity only, and then fires its thrusters. From the moment the thrusters are one, the rocket has a net acceleration of 5.481 direscted 30.21 degrees above the horizontal. How far apart are the plane and the rocket when the rocket passes back through the cruising altitude of the plane?

Rod OA rotates counterclockwise with a constant angular velocity of = 5 rad/s. The double collar B is pin connected together such that one collar slides over the rotating rod and the other slides over the horizontal curved rod, of which the shape is described by the equation r = 1.5(2 - cos θ) ft. If both collars weigh 0.75 lb, determine the normal force which the curved rod exerts on one collar at the instant θ = 120o. Neglect...

a constant velocity horizontal flow grit channel is discharging unacceptable amounts of grit into the primary facultative pond of a stabilization pond. In addition the channel overtops regularly with peak wet weather flow during normal rain storms. An initial investigation confirmed levels of grit present in the particular wastewater to be within normal loading levels. Furthermore, the provision for grit storage capacity in the channel is adequate for the operational cleaning-out cycle employed. According to the authorities, the likely cause...
