NUCL 273 Scope of Test-1 (Tue-Feb24, PHYS 112, 8:00PM-9:30PM) First Two Chapters – Normal, Shear Stresses – Axial Loading – Deformation – General Loading – Statics – Stress-Strain Relationship – Statically Indeterminate Problems – Hooke’s Law, Poisson’s ratio – Thermal Stresses
NUCL 273 Problem 1 MPa U 400 = σ 1. Link BD Consists of a single bar 30 mm wide and 12 mm thick. Each pin has 10 mm diameter and is in single shear. For θ = 0 ° , calculate a. The force on link BD b. The maximum value of the normal stress in link BD c. The shear stress in pin B d. The minimum factor of safety if e. Repeat a, c, d for θ = 90 ° MPa U 380 = τ
