For general engineering design, it is not necessary to achieve such analysis precision.
It is clearly not desirable for spending a lot of time to solve equations in practical engineering.
High strength bolts of M20 are used in the engineering.
By the calculation bolt sphere joints diameter is taken as 100mm in the engineering.
