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.

The roughly position of the automobile jack shown in the figure is a square screw with a single blade at both ends. ABC is controlled by a bolt (right-hand threaded in A, left-handed in C). square of the bolt screw has a pitch of 2.5 mm and an average diameter of 9 mm. between the bolt and the jack limbs The coefficient of static friction is 0.15, taking into account the position and load shown, you can use the jack Find the magnitude of the torque that must be applied to raise it.

A cross belt system gives a speed reduction of 6:1 and the centre distance between the pulleys is 2.5 m. The effective radius of the driving pulley is r, = 80 mm and it runs at the speed of 550 rpm. The grove angle of pulleys is 25°. The belt has a mass of 0.35 kg/m and the coefficient of friction of 0.3. If the tension in the belt is not to exceed 650 N, calculate the power that can be transmitted by drive.
