    An HRT boiler is 4766mm long and 3533mm in diameter. It has 66 steel tubes with a diameter of 9mm. The total dry weight of the boiler is 2.565 tonnes. 4 bolts are to suspend the boiler. If each bolt has to be strong enough to support 1/2 the weight of a filled boiler, what will be the diameter of the bolts?

    Note: each bolt must not exceed 86 MPA.

    First, we need to solve the volume and mass of each steel tubes.
    density_steel = mass / Volume_tube
    where,
    density_steel=7850 kg/m^3 = 7.85 * 10^-6 ...
