A bracket connection is made with four bolts of $$10$$ $$mm$$ diameter and supports a load of $$10$$ $$kN$$ a an eccentricity of $$100$$ $$mm.$$ The maximum force to be resisted by any bolt will be

A steel flat of rectangular section of size $$70 \times 6\,\,mm$$ is connected to a gusset plate by three bolts each having a shear capacity of $$15$$ $$kN$$ in holes having diameter $$11.5$$ $$mm.$$ If the allowable tensile stress in the flat is $$150$$ $$MPa,$$ the maximum tension that can be applied to the flat is

An axially loaded bar is subjected to a normal stress of $$173$$ $$MPa.$$ The maximum shear stress in the bar is

The shear stress at the neutral axis in a beam of triangular section with a base of $$40$$ $$mm$$ and height $$20$$ $$mm,$$ subjected to a shear force of $$3$$ $$kN$$ is
