A reinforced circular column of 400 mm diameter has 4 steel bars of 20mm dia. embedded in it. Find the maximum load which the carried by column, If the stresses in steel and concrete are not exceed 12 Mpa and 5 Mpa respectively. Take modulus of elasticity of steel as 18 times the concrete.​

Answer: 1.4 seconds which is the third optionexplanation: current is defined as the flow of charge per timetherefore, the equation that relates current, charge and time can be expressed as follows: i = δq / δtwhere: i is the current given = 1.8 ampereδq is the charge given = 2.5 coulombδt is the time required for the flow of the given charges to give the 1.8 ampere.substitute with the givens in the above equation to get the time as follows: 1.8 = 2.5 / δtδt = 2.5 / 1.8 = 1.38888 which is approximately 1.4 secondshope this was !
