121 A circular aircraft window made from polycarbonate is clamped at its edge and will experience a uniformly distributed load due to the pressure difference between the cabin and the external environment. Specifications for the window are given in Table Q2 below. (b) If the pressure difference during flight is P 75 + 1 kPa, use the equation below to calculate the deflection, w, at the centre of the window and the uncertainty in this result 114] Deflection of circular...
This bracket is to be built from a 20 mm thick steel plate that is 100mm high and 200mm wide. Calculate neglecting the hold the place of maximum deflection and how much when a load of 1Mpa is applied to the right side of the plate. Then calculate the amount and point of maximum stress including the hole. (20mm diameter for the hole sorry with a center position of 100mm from the left side and 50mm from the bottom) deflection...
An aluminum alloy (2024) plate, heated to a uniform temperature of 227°C, is allowed to cool while vertically suspended in a room where the ambient air and surroundings are at 27°C. The plate is 0.3 m square with a thickness of 15 mm. a) calculate the rate of heat transfer from the plate to the surrounding air. b) Develop an expression for the time rate of change of the plate temperature, assuming the temperature to be uni form at any...
