Axial Load

When a bar of the uniform cross-section is acted by a load, such that the load acts along the longitudinal axis of the bar, such kinds of loadings are known as axial loadings. In general terms, a load is an external force acting on a component. An axial load acts perpendicular to the geometric cross-section of the component. Based on the direction of the application of the load, an axial load can be tensile or compressive. The analysis of bodies under the action of axial loads is generally studied under the branch of mechanics, known as statics.

Question

A governor of the Proell type has each
arm 250 mm long. The pivots of the
upper and lower arms are 25 mm from
the axis. The central load acting on the
sleeve has a mass of 25 kg and the
each rotating ball has a mass of 3.2 kg.
When the governor sleeve is in mid-
position, the extension link of the
lower arm is vertical and the radius of
the path of rotation of the masses is
175 mm. The vertical height of the
governor is 200 mm. If the governor
speed is 160 r. p.m. when in mid-
position, find: 1. length of the
extension link; and 2. tension in the
upper arm.

The reciprocating masses of the first three cylinders of a four cylinder engine are 4.1, 6.2 and 7.4 tonnes respectively. The centre lines of the three cylinders are 5.2 m, 3.2 m and 1.2 m from the fourth cylinder. If the cranks for all the cylinders are equal, determine the reciprocating mass of the fourth cylinder and the angular position of the cranks such that the system is completely balanced for the primary force and couple. If the cranks are 0.8 m long, the connecting rods 3.8 m, and the speed of the engine 75 r.p.m. ; find the maximum unbalanced secondary force and the crank angle at which it occurs. solve graphically
The mechanism shown is a special platform used to raise sections of a structure for the construction of a tower. Assembly A has a mass of 3000 kg and is lifted by platform B which has a mass of 2000 kg. The platform moves upwards guided by the vertical column by means of rollers, as the movement is activated by the hydraulic piston CD and the parts EDF and FH. For the position shown, determine the magnitude of the minimum force that must be exerted by the hydraulic piston to start the lifting motion.
