A rectangular concrete beam has a width of $0\mathrm{.}3$ m and a depth of $0\mathrm{.}5$ m$.$ If the allowable stress in concrete is $7$ MPa, calculate the maximum bending moment the beam can resist. Use the formula M $=(1/6)*$ $*$ b $*$ d$^2.$ Determine the value of the maximum bending moment using the given dimensions and allowable stress. Round your final answer to two decimal places, and express the result in appropriate units.
