4 m लंबाई का एक सरल समर्थित धरन (simply supported beam) पूरे स्पैन पर 2 kN/m का एकसमान वितरित भार (UDL) वहन करता है। E = 200 GPa और I = 4 × 105 mm4 मानते हुए धरन का अधिकतम ढाल (slope) क्या होगा?

The principal strains recorded for a rectangular panel subject to biaxial loading are ε11 = 100 × 10-6 and ε22 = -50 × 10-6. The magnitude of maximum shear strain is ____ × 10-6.

A steel rod of length 1 m is fixed at one end and free at the other end. It is subjected to a temperature rise of 20°C. If the coefficient of thermal expansion of the material is 20 × 10-6/°C, what is the thermal strain produced in the rod (in terms of × 10-6)?
