What does tin and lead make?
Tin and lead makes pewter
Examples of mechanisms in the home?
Examples of mechanisms in the home include door hinges, which allow doors to swing open and closed; light switches, which control the flow of electricity to turn lights on and off; and faucets, which regulate the flow of water. These mechanisms all involve moving parts that perform specific functions within the home environment.
What metal alloy does tin and lead make?
Definition - Terne is an alloy coating of lead and tin used to cover steel, in the ratio of 20% tin and 80% lead. Terne is used to coat sheet steel to inhibit corrosion. It is the one of the cheapest alloys suitable for this, and the tin content is kept at a minimum while still adhering to a hot-dipped iron sheet, to minimize the cost.
How were steam engines used in the past?
Steam engines were first used in the tin mines of Cornwall, England to pump water from the mines which often extended out under the Cornish coastline.
How do you convert a hardness number into tensile strength?
Tensile strength calculation for Finger cots and Condom:-(RING TYPE)Tensile strength Formula : F/A (N/mm2)Where :- F - Force (N)A- cross sectional area (mm2)A- cross sectional area - Width *thickness (single wall)So F/2(width * thickness) (N/mm2)For Example :-F= 35.963 Nwidth = 6.35 mm (specimen width standard in finger cots)Thickness = 0.12 mmCalculation:-= F/ 2(Width *Thickness) (N/mm2)Where 2 is common factor for ring samples .= 37.963 / 2(6.35*0.12) (N/mm2)= 37.963 /1.524 (N/mm2)= 24.91 (N/mm2) this is good answer for finger cots and condom Tensile strength calculation.You stretch test specimens in a prescribed manner (ASTM) and make note of what force failure occurs. The tensile strength is that force divided by the cross-sectional area.
