The weight of the steel coil is P. a) Write the expression for the direct stress, o, in the cable. b) The strain energy, e, stored in the cable is e= (oedV,
b a h Exercise 1.3 1.4 Strain Energy The steel coils of Exercise 1.1 are unloaded by a crane with a steel cable which has an equivalent cross section area A
1. COMPLEX STRESS. TUTORIAL 5. STRAIN ENERGY. This tutorial covers parts of You should judge your progress by completing the self assessment exercises.
Equating y = 0 m or 1 mm. SELF ASSESSMENT EXERCISE No. Determine the strain energy and for the beam shown and determine the deflection under. the load. The
(b) For uniaxial stress in the 1-direction, σ1, the strains are: E. 1. 1 Thus 14% of the acoustic power is transmitted into the steel, 86% is reflected.
Exercise 3: Figure 3 shows a stress vs strain plot for a rubber band. As it is stretched (loaded), the curve takes the upper path. Because the rubber band is
For most materials, the strain experienced when a small stress is applied depends Exercise 1: A 75 kg person stands on a compression spring with spring
The Young modulus of steel is 2.1 × 1011 Pa. Calculate: (i) the force exerted on the walls by the rod;. (3). (ii) the elastic strain energy in the rod when
