Acylindrical rod of copper (e = 110 gpa, 16 × 106 psi) having a yield strength of 240 mpa (35,000 psi) is to be subjected to a load of 6660 n (1500 lbf). if the length of the rod is 380 mm (15.0 what must be the diameter to allow an elongation of 0.50 mm (0.020

7.65 mm

Explanation:

Stress, where F is the force and A is the area

Also,

Where E is Young’s modulus, L is the length and is the elongation

Therefore,

Making A the subject of the formula then

Since then  

the equation above shows how temperature f, measured in degrees fahrenheit, relates to a temperature c, measured in degrees celsius. based on the equation, which of the following must be true?

a temperature increase of 1 degree fahrenheit is equivalent to a temperature increase of

5

9

degree celsius.

a temperature increase of 1 degree celsius is equivalent to a temperature increase of 1.8 degrees fahrenheit.

a temperature increase of

5

9

degree fahrenheit is equivalent to a temperature increase of 1 degree celsius.

a) i only

b) ii only

c) iii only

d) i and ii only
