    maximum shear stress = 675 kPa

    Explanation:

    Given data

    wide section b = 5 cm

    deep section d = 10 cm

    shear = 2250 N

    to find out

    the maximum shear stress in the beam

    solution

    we know the maximum shear stress in the beam formula that is

    maximum shear stress = 3/2 * shear / b d

    maximum shear stress = 3/2 * 2250 / 50*100

    maximum shear stress = 0.675 N/mm²

    maximum shear stress = 675 kPa
