The below figure shows the two equal forces at right angles acting at a point. The value of force 'R' acting along their bisector and in opposite direction is According to Euler's column theory, the crippling load for a column of length ($$l$$) with one end fixed and the other end hinged, is The value engineering technique in which experts of the same rank assemble for product development is called The logarithmic mean temperature difference ($${{\text{t}}_{\text{m}}}$$) is given by (where $$\Delta {{\text{t}}_1}$$ and $$\Delta {{\text{t}}_2}$$ are temperature differences between the hot and cold fluids at entrance and exit) A steel bar 2 m long, 20 mm wide and 10 mm thick is subjected to a pull of 2 kN. If the same bar is subjected to a push of 2 kN, the Poisson's ratio of the bar in tension will be __________ the Poisson's ratio for the bar in compression.
