For the beam and loading shown, determine the range of the distance a for which the reaction at B does not exceed 100 N downward or 200 N upward.
A bar of length 1000 mm and diameter 30 mm is centrally bored for 400 mm, the bore diameter being 10 mm as shown below. Under a load of 30 kN, if the extension of the bar is ...Read more
A bar of 25 mm diameter is tested in tension. It is observed that when a load of 60 kN is applied, the extension measured over a guage length of 200 mm is 0.12 mm and contraction in ...Read more
A composite bar is made up by connecting a steel member and a copper member rigidly fixed at their ends. The cross-sectional area of steel member is A cm2 while that of the copper member is 2A cm2 ...Read more
