Below Fig. shows a rigid bar hinged at A and supported in a horizontal position by two vertical identical steel wires. Neglect the weight of the beam. The tension $${T_1}$$ and $${T_2}$$ induced in these wires by a vertical load P applied as shown are GATE ME 1994 Strength of Materials - Simple Stress and Strain Question 15 English
A
$${T_1} = {T_2} = {P \over 2}$$
B
$${T_1} = {{Pal} \over {\left( {{a^2} + {b^2}} \right)}},{T_2} = {{Pbl} \over {\left( {{a^2} + {b^2}} \right)}}$$
C
$${T_1} = {{Pbl} \over {\left( {{a^2} + {b^2}} \right)}},{T_2} = {{Pal} \over {\left( {{a^2} + {b^2}} \right)}}$$
D
$${T_1} = {{Pal} \over {2\left( {{a^2} + {b^2}} \right)}},{T_2} = {{Pbl} \over {2\left( {{a^2} + {b^2}} \right)}}$$
