Atensile test on a 10 mm diameter specimen registered failure under a load of 32.6 kn. what force would be sufficient to break a 1.5 mm diameter wire made from this material?

0.7315 kN

Explanation:

We have given diameter = 10 mm , so radius =

The specimen registered failure under a load of 32.6 kN

So load = 32.6 kN

We know that here is the maximum stress which the material can withstand

Now for diameter d=1.5 mm

radius

load =0.7315 kN

the warning light flashes for a second or two when the engine starts. if it stays on, there's must be something wrong with the coolant. you should never dare to continue driving when the light is on. pull over as soon as possible and shut the engine off.

hope this is what you're talking about

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
