Bars of Composite Section

Bars Of Composite System

A rectangular bar is uniformly loaded axially with force per unit area sigma shown. Shown is a section A A' in the bar. Normal stress for the section is

The photograph given as Fig. shows a section of a grille made up of straight and curved iron bars. How would you measure the length of the bars of this section, so that the payment could be made to the contractor?

the position vector of the centre of mass lt to r cm of an asymmetric uniform bar of negligible area of cross - section as shown in figure is :

The magnetic field of 20CGS units produces of a flux of 2400 CGS units in a bar of cross section 0.2cm^(3) Calculate the (i) permeability and (ii) susceptibility of the bar.

A magnetising field fo 1000 A/m produces a magnetics flux of 2.4 xx10^(-5) Wb in an iron bar of cross sectional area 0.3 cm^(2) what is the magnetic permeability of the iron bar ?

A steel bar of cross section A is subjected to two equal and opposite pulling forces at the two ends. If there is a plane through the bar making an angle alpha as shown, find the shearing stress at this plane

A bar of mass m and length l is hanging from point A as shown in the figure . If the Young's modulus of elasticity of the bar is Y and area of cross - section of the wire is A, then the increase in its length due to its own weight will be

A steel bar of cross section A is subjected to two equal and opposite pulling forces at the two ends. If there is a plane through the bar making an angle alpha as shown, find for what alpha the shearing strain is maximum.

A bar of mass m and length l is in pure translational motion with its centre of mass moving with a velocity v. It collides and sticks to another identical bar at rest as shown in the figure. Assuming that after the collision the system of the two bars becomes one composite bar of length 2l, then the angular velocity of the composite bar will be
