Q. A beam has triangular cross-section, having base 'b' and altitude 'h'.If a section of the beam is subjected to a shear force F, the shear stress at the level of neutral axis in the cross-section is given by

1. $\frac{4F}{3bh}$
2. $\frac{3F}{4bh}$
3. $\frac{8F}{3bh}$
4. $\frac{3F}{8bh}$

Q. A beam has a triangular cross-section having base 40 mm and altitude 60 mm. If this section is subjected to a shear force of 36000 N, the maximum shear stress in the cross-section would be

2. $36N/m{m}^2$
3. $45N/m{m}^2$
4. $30N/m{m}^2$
