Thermal Properties of Materials

In mechanical engineering, the thermal property is represented as the physical quantity that is relevant to the application of heat. The thermal properties are evaluated by variations in any specific material due to low heat or high heat. The quantities that influence the thermal property of the materials are mass, density, temperature, and many others.

QA5- GENERAL PLANAR MOTION (USING NEWTON'S 2ND LAW & EULER'S EQUATION)
For the purposes of calculating its inertia, the body of a micro-satellite can be considered to be a
uniform rod of length 1 m and mass 15 kg. The satellite is required to move such that its centre of
mass, G, has a linear acceleration of 1.5 m/s in a direction perpendicular to the satellite (rod), and it
has an angular acceleration of 2 rad/s about an axis perpendicular to both the satellite and to the
direction of the linear acceleration of G. Find a single thrust vector (force) that will cause this, and
where on the satellite this must be applied.
Hint: Draw a free-body diagram of the satellite (rod), clearly showing the thrust vector, linear
acceleration, and angular acceleration. Due to Newton's 2nd law, the thrust vector must act in the
same direction as the linear acceleration.

Learning Goal: A material is homogenous and isotropic when it has a modulus of elasticity that does not vary with direction and it has uniform properties throughout. When a point in a material is subjected to only normal stresses in three dimensions, but they are not necessarily equal, the state is called triaxial stress. When the response of the material is linear elastic, the strains along the three axes can be calculated using a generalized form of Hooke's law. Each strain depends on all three stresses because of the Poisson effect. €1 Figure 1 [0₂ - V (O₂ +0₂)] a 1 of 1 A cube is subjected to stresses with magnitudes a = 16 MPa, b = 26 MPa, and c = 5 MPa (Figure 1).
