Often taken as one-third of the allowable working stress in tension. Let's assume that the allowable working stress in tension for the steel rod is 150 MPa.

The cross-sectional area of the steel rod can be calculated as follows:

A = P/σ

where A is the cross-sectional area, P is the tensile load, and σ is the allowable working stress in tension.

A = 150,000 N / (150 MPa) = 1,000 mm²

The allowable working stress in shear can be calculated as one-third of the allowable working stress in tension:

σ_shear = σ_tension / 3

σ_shear = 150 MPa / 3 = 50 MPa

Therefore, the allowable working stress in shear for the steel rod is 50 MPa.
