Q$2)$ A tentilever beatn with $3$ m span has rectangular gection $(h=500mm,d=410mm)$ and carries uniform factored loal $80.k\frac{N}{m}($including self$-$weight$),$ as shown in Fig$(2),$ Uaing fo$-28$ MPa, normal$-$weight conerete and f$)=420$MPa to determine:

Taking the effect of placing the uniform distributed factored live load $50k\frac{N}{m}$ to produce maximum shear and check if the concrete section is adequate to resist the applied shear force.

Cilculate the requined atimp for suitable section to resist applied shear force if the uniform distributed fiactored live lood is $100k\frac{N}{m}in.($notes$.$ It is allowed to change depth $10\%$
