Q2: A spacer is turned from Aluminum alloy with elasticity modulus of 78 GN/m². The spacer has a diameter of 28 mm and a length of 245 mm. both measurements being made at 20°C. The temperature of the spacer is then increased to 100 °C, the natural expansion being entirely prevented. Taking the- coefficient of linear expansion to be 18 x 10-6 /°C. Determine the compressive load on the spacer

In dead weight tester, the applied load is 0.017 kN, theoretical pressure is 150 kPa. Then the area of cylinder is approximately

WHATSAPP now Ali Janbein @ cuumi Problem 2: The short cylindrical block of 2014-T6 aluminum, having an original diameter of 0.5 in. and a length of 1.5 in., is placed in the smooth jaws of a vise and squeezed until the axial load applied is 800 lb. Given young's modulus 10.6x10 psi and Poisson ratio equal to 0.35. a) Determine the decrease in its length b) Determine its new diameter. 800 Ib 800 I Solution: Problem 3: A rectangular rod made of an aluminum alloy is subjected to a tensile force Falong its longitudinal axis. The rod has an initial length Le-Im and a rectangular cross-section with initial width w - 20 mm and initial height 25 mm. The mechanical properties of the aluminum alloy are: - Modulus of Elasticity E-100 GPa - Yield stress YS - 320 MPa Poisson's ratioy03 1. Ifa force F 80AN is arpliedto the rod determine the final lensth the with w and height h of the cross sectionn What is the maximum foroe Fthat can be drfrmatim

please show a step by step solution, thank you! What is the whal factor of a spring if it has the characteristics average diameter 200 mm, wire spring diameter 30mm, modulus of rigidity is 70 GPa and there is 85 turns in the spring. Answer in 4 decimal places
