Welcome to your Engineering Materials
It is the measure of the resistance to twisting.
Kinematic viscosity in SI derived unit is described as:
A cylinder pressure vessel is fabricated from plates which have a thickness of 20mm. The diameter of the pressure vessel is 450 mm and its length is 3.5m. Determine the maximum internal pressure which can be applied if the stress in the steel is limited to 150MPa.
A steel rod 2.5 m long is secured between two walls. If the load on the rod is zero at 20 degree Celsius, compute the stress when the temperature drops to -20 degrees Celsius. The cross-sectional are if the rod is 1200 sq. mm, coefficient of linear expansion = 11.7 um/(m-deg.C), and E = 200 GPa. Assume that the walls are rigid.
It is the value of stress on the stress-strain curve at which there is a significant increase in strain with little or no increase in stress
It is the maximum safe stress that a material can carry
Determine the elongation in a helical steel spring composed of 20 turns of 20 mm-diamter wire on a mean radius of 80 mm when tha spring is supporting a load of 2 kN. Use G = 83 GPa
Internal force that acts against distortion
It occurs when a cutting action is applied as you would see with scissors, tin snips, or punches
The hardness of steel may be increased by heating to approximatelyv1500°F and quenching in oil or water if
The point through which the resultant of the disturbed gravity force passes regardless of the orientation of the body in space is called:
A steel rod having a cross-sectional area of 300 sq. Meters and a length of 150 m is suspended vertically from one end. It supports a tensile load of 20 kN at the lower end. If the unit mass of steel is 7850 kg/m^3 and E = 200×10^3 MN/m^2, find the total elongation of the rod
A solid steel shaft 5 m long is stressed to 80 MPa when twisted through 4 degrees. Using G = 83 GPa, compute the shaft diameter.
It is the internal resistance offered by a unit area of the material from which a member from which a member is made to an externally applied load
A steel bar 50 mm in diameter and 2 m long is surrounded by a shell of cast iron 5 mm thick. Compute the load that will compress the combined bar a total of 0.8 mm in the length of 2m. For steel E = 200 GPa, and for cast iron E = 100 GPa
It is a measure of pulling and pushing force
It is the point at which there is an appreciable elongation of the material without any corresponding increase of load.
A leak from a faucet comes out in separate drops. Which of the following is the main cause of this phenomenon
A process of welding metals in molten or in vaporous state without application of mechanical pressure or blow. Such welding may be accomplished by the oxyacetylene or by hydrogen flame or by electric arc. It is called:
It is the ability of a material to be elongated
