Being an irregular student is generally defined as a student who does not follow the regular schedule of attending classes, taking exams, or fulfilling the academic requirements within the expected timelines. Most students are expected to graduate within a certain period or academic years, and… Read More »Is It Okay to be an Irregular Student? Advantages and Disadvantages
The aluminum block has a rectangular cross section and is subjected to an axial compressive force of 8 kip. If the 1.5-in. side changed its length to 1.500132 in., determine Poisson’s ratio and the new length of the 2-in. side. E AL = 1 0… Read More »The aluminum block has a rectangular cross section and is subjected to an axial compressive force of 8 kip. If the 1.5-in
If the force P causes the rigid arm ABC to rotate clockwise about pin A through an angle of 0.02°, determine the normal strain in wires BD and CE.
When force P is applied to the rigid arm ABC, point B displaces vertically downward through a distance of 0.2 mm. Determine the normal strain in wire CD.
An aluminum bar having a cross-sectional area of 0.5 𝑖𝑛 carries the axial loads applied at the positions shown in the figure. Compute the total change in length of the bar if 𝐸 = 10 × 10 𝑝𝑠𝑖. Assume the bar is suitably braced to… Read More »An aluminum bar having a cross-sectional area of 0.5 𝑖𝑛 carries the axial loads applied at the positions…
The rigid pipe is supported by a pin at A and an A-36 guy wire BD. If the wire has a diameter of 0.25 in., determine the load P if the end C is displaced 0.15 in. downward.
The objective of this research study is to elaborate on the cause of the incident involving a Boeing 757-21B that occurred on the last 7th of September, the year 2011, in the cruise of Bulgarian airspace. This report includes the failures found, underlying issues, contributing factors that prompt… Read More »Boeing 757-21B Aircraft Incident Report: Flight Instruments’ Electrical Failure
The rectangular plate is deformed into the shape of a parallelogram shown by the dashed line. Determine the average shear strain at corner A with respect to the x and y axes.
Determine the average normal stress in rod AB if the load has a mass of 50 kg. The diameter of rod AB is 8 mm.
The rigid bar ABC in the figure is pinned at B and attached to the two vertical rods. Initially, the bar is horizontal and the vertical rods are stress-free. Determine the stress in the aluminum rod if the temperature of the steel rod is decreased… Read More »The rigid bar ABC in the figure is pinned at B and attached to the two vertical rods.
