एक पतले बेलनाकार शेल का हूप प्रतिबल (hoop stress) 45.76 N/mm2 है। समान आंतरिक दाब पर उसी बेलन के लिए अनुदैर्ध्य प्रतिबल (longitudinal stress) ज्ञात कीजिए।

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)?
