BTEC Level 3 Unit 8 Mechanical Principles Assignment: Static Force Analysis and Stress Calculations in Engineering Systems

University University of Glasgow
Subject Unit 8: Mechanical Principles and Applications

Vocational Scenario or Context

The use and application of mechanical systems is an essential part of modern life. The design, manufacture and maintenance of these systems are the concern of engineers and technicians who must be able to apply a blend of practical and theoretical knowledge to ensure that systems work safely and efficiently. Science underpins all aspects of engineering and a sound understanding of its principles is essential for anyone seeking to become an engineer. Having completed learning outcome LO8.1 of Mechanical Principles of Engineering Systems in your course at Newham College, you are required by your employer to demonstrate your understanding in effects of loading in static engineering systems particularly effects of mechanical force on solids. To do this complete the tasks below.

Task 1

Statics

Calculate the magnitude, direction and position of the resultant force and turning moment about point  for the system of forces acting on the bridge support plate shown in figure 1. What would be the equilibrant force and its direction? P1

Task 3

  • Component subjected to direct uniaxial loading

The rectangular steel bar, figure 3 is part of a static test rig and extends under a tensile load of  kN. If the elastic modulus  for the steel material is 208 GN/m2, calculate:

  1. the stress in the bar,
  2. the resulting strain, and
  3. the extension of the bar. P3

  • Component subjected to shear loading

A rivet which has a diameter D mm is being used to hold together the sides of a storage vessel and is subject to the loadings shown in the figure 4. Calculate:

  1. the resulting shear stress
  2. the resulting shear strain if the shear modulus for the rivet material is 79 GN/m2. P3
