When a bar in a truss or frame is receiving a force that squeezes it inward on itself, that bar is said to be experiencing..
What is compression?
A vector is defined by these two qualities
What are magnitude and direction?
The area under the temperature-entropy curve (T – s curve) of any thermodynamic process represents
either heat absorbed or heat rejected
The matter contained within a body is also known as this.
The sum of internal energy (U) and the product of pressure and volume (p.v) is known as
A body of weight W is required to move up on rough inclined plane whose angle of inclination with the horizontal is α. The effort applied parallel to the plane is given by(where μ = tanφ = Coefficient of friction between the plane and the body.)
What is P=W(sinα+μcosα)?
A mixture of gas expands from 0.03 m^3 to 0.06 m^3 at a constant pressure of 1 MPa and absorbs 84 kJ of heat during the process. The change in internal energy of the mixture is
