A completely reversed axial load of 20 kN is applied to a machine finished plate (BS 080M50, HR) as shown in the figure. Determine the size b of the plate for indefinite cycle of operation based on Goodman equation. Consider b = 10d = 10t. Choose safety factor of 1.5 and reliability of 99%.
The welded cantilever is subjected to a cyclic torsional load of Tmax = 2 kN-m and Tmin = 1 kN-m. The material is AISI 1018 CD. Calculate: Fatigue safety factor according to Gerber criterion. Consider 90% reliability and stress concentration at end of parallel fillet weld.
A thick walled cylinder is subjected to a fluctuating internal pressure of 0 to 100 MPa. The outer and inner diameters of the cylinder are 250 mm and 150 mm, respectively. The material is Ferritic-pearlitic steel with Sut = 800 MPa and Sy = 600 MPa. The fracture toughness of the material is 50 MPa√m. The ultrasonic detector detects a nick of 0.2 mm (as shown in the following figure). Estimate the No. of cycles life remaining of this cylinder.
A machine part is loaded as shown in the following figure. The moment, M varies from -10 kN-m to +20 kN-m and the force, F varies from 0 to 10 kN. The material is AISI 1040 annealed steel. Consider, machined surface, 100° Celsius temperature operation, 95% reliability. Determine the minimum factor of safety for this part based on Soderberg equation. Given that, d = 50 mm and thickness of the part t = 20 mm.

Create a program that will String input. Based on the number of inputs,
the USER will decide what shape it is circle,rectangle,square and triangle.
(1 input – circle, 2 inputs – square or rectangle, 3 inputs - triangle).
The program will then display the shape type, details, perimeter and area.
