Question

In an ally cu,tin,lead is 8:5:3.The total quantity ​of weight is 280kg,then find the quantity of cu​

Answer 1

Answer:

Step-by-step explanation:

8x+5x+3x = 280kg

16x = 280kg

x= 17.5

Quantity Of cu = 8(17.5) = 140kg

Answer 2

ANSWER:

8x+5x+3x = 280kg

16x= 280kg

x= 17.5

Quantity Of cu = 8(17.5) = 140kg

Step-by-step explanation:

Tin as an addition element raises tensile strength, tarnish resistance and wear resistance of Cu-Ni alloys. Cu-Ni alloys containing c. 2% Sn are distinguished by very good resistance to stress relaxation and therefore are used a spring materials. Alloys with even higher tin contents (4 to 10%) can also be age-hardened
