At an axial load of 22 kN, a 15-mm-thick x 35-mm-wide polyimide polymer bar elongates 4.6 mm while the bar width contracts 0.25 mm. The bar is 230-mm long. At the 22-kN load, the stress in the polymer bar is less than its proportional limit. Determine Poisson's ratio.

(5) In order to forge a pure gold ring, you first need to purchase the gold. The ring design is a simple band wrapped in a circle, with dimensions given below. Using the Pappus-Guldinus Theorem #2, how many grams of gold are needed for this ring? The density of gold is 19.3 g/cm³. 2 cm 1 cm 0.5 cm 0.5 cm

What are the concentrated forces?

Determine the x, y, z components of reaction at the journal bearing C if 0 = 0°.

Select the correct statements regarding moment and torque.  (Select 3) Moment and Torque are two different phenomena, hence SI- units are different   Generally Moment is used when there is no rotation, while torque is used when there is rotation.   Moment and torque are very similar concepts and are sometimes interchangeable   Moment and Torque are calculated by force multiplied by its distance to the reference point.

The attached answer was provided for the attached question. The equation uses the given temperature in celcius and the answer is also given in celcius. The temperature was used in the equation without converting from F and the answer was supposed to be in F. I am worried that even if I converted the answer to celcius that it would be correct because temperature was used in the equation using the incorrect unit.
