Concept explainers

Slope and Deflection

The slope in a deflected beam is described as an angle in radians made by the tangent of the section with the original axis of the beam. The deflection at any point on the axis of the beam is defined as the lateral displacement of the point before and after loading.

Q2) A loaded Porter governor has four links each 200 mm long and are hinged at a distance of 40 mm from the axis of rotation. The mass of each ball is 2 kg and mass of the sleeve is 20 kg. The governor sleeve begins to rise at 300 r.p.m. when the links are at an angle of 35° to the vertical. Assuming the friction force to be constant, determine the minimum and maximum speed of rotation when the inclination of the arms to the vertical is 40°.

A car A is stuck on the railroad tracks as a train B approaches with a speed of 120 km/hr. As soon as the problem is detected, the train's emergency brakes are activated, locking the wheels and causing the train's wheels to slide relative to the tracks. If the co-efficient of kinetic friction between the wheels and the track is 0.2, use work energy principle to determine the minimum distance d at which the brakes must be applied to avoid a collision under the following circumstances. Mass of the train is 195,000 kg. A B d
