2.Discuss elastic region in a tensile test and shear test. It is always linear. What is engineering stress, strain ? Give Hooke's law, for tensile and shear deformation with corresponding modulus.

Why should the loading be linearly related to the stress or Displacement that is to be determined?

The overhead beam in the figure has the composite section given below. The bending moment vector acts at an angle of 0-60 degrees with the horizontal z-axis of the beam section as shown in the figure. Determine the stress at point K of the beam section for the maximum bending moment under the forces acting on the beam. Note: The numerical values of the relevant parameters are given in the attached table for each student. K Z< M 0 40mm 395 mm B2 40mm B1 240 mm + 45 mm H 180 mm 45 mm 32 KN -1.6 m B 2.4 m с 36 kN/m 6.4 m D

Draw the three Mohr's circles that describe the state of stress in (Figure 1). Figure 1 of 1 > 25 ksi 25 ksi

Solve Clearly!!!!z,

Explain with a sketch the method which is used to compute the stress ratio.

Below two stress strain curves are drawn to scale. Explain the advantage/disadvantage of material A vs. B.

The maximum tensile stress o, from bending of a simply supported beam with length L and circular cross section with diameter D, is given by the expression 8FL , where F is the magnitude of a concentrated force acting in the middle of the beam. If the relative error in estimating the magnitude of the concentrated force F is 10%, the relative error in measuring the length of the beam L is 5% and the relative error in measuring the diameter D of the beam is 2%, estimate the relative error in the maximum tensile stress o.
