The formula below is used to calculate the Normal stress: Normal stress=Axial force/Cross-Sectional Area σ =P/A Normal stress will occur when an object is placed in tension or compression. Longitudinal Stress When the length of the body changes its length by normal stress that is applied ...

If we were to evaluate the sums of weights times heights, it would not check out—we must add something else to account for the fact that the spring is under tension. Elastic energy is the formula for a spring when it is stretched. How much energy is it? If we let go, the elastic...

For example, if the material is brittle, the engineer might use Mohr's circle to find the maximum component of normal stress (tension or compression); and for ductile materials, the engineer might look for the maximum shear stress. Stress in three dimensional bodies Cauchy's principle Cauchy...

The formula for the wave speed in the string is calculated by the dimensional analysis. The dimension of Mu is [ML-1] and with tension T, it would be [MLT-2]. When we combine these dimensions, then we get the speed v which has dimension [LT-1]. Let us assume tension(T) and lin...
the tension in the string, and friction because the tabletop is not frictionless. Tension and friction are both doing work. Since the velocity is constant, the applied force has to be countered by an equal friction force in the opposite direction. If the force varies, the distance the mass ...
