Concept explainers

Buckling of columns

The column is described as a vertical member of the structure that carries an axial compressive load, and buckling is a lateral deformation of the column under the application of load.

The pedal and brake drum are illustrated in Figure Q2(b). The 160 mm radius brake drum is attached to a larger flywheel (not shown). The total mass moment of inertia of the flywheel and drum is 20 kg-m? and the coefficient of kinetic friction between the drum and the brake shoe is 0.35. The initial angular velocity of the flywheel is 360 rpm counterclockwise. If the system is to stop in 100 revolutions, determine the vertical force P that must be applied to the pedal C. (Hint: Draw a free-body diagram for the brake drum and pedal, separately and label all the forces)
