find out stress - strain and elongation of bara circular rod having diameter 20 m and 500 m long is subjected to the tensile force of 45kn the
give differences between direct stress and bending stressdirect tensile and compressive stress is set up because of load applied parallel to length
neutral layer and neutral axisin the beam or cantilever there is one layer which retains the original length of it even after bending so in this
find out diameter of steel wireq a load of 5 kn is to be raised with help of steel wire find out diameter of steel wire if maximum stress does not to
write down the different assumptions in simple theory of bending the
what is bending stressthe bending moment at section tends to bend or deflect beam and internal stresses resist its bending the process of bending

theorem of parallel axisit states that if the mi of plane area about the axis passing through the cg can be denoted by ig the mi of area about any
explain youngs modulus or modulus of elasticitysol it is ratio between tensile stress and tensile strain or compressive stress and compressive
theorem of perpendicular axisit states that if ixx and iyy be the mi of plane section about the two mutually perpendicular axes meeting at a
state hooks lawsol it states that when material is loaded within the elastic limit the stress is proportional to strain produced by the stress this
elastic limitsol when external force acts on the body the body tends to undergo some deformation if external force is removed and body comes back to
