What is the work required to deflect a linear spring (k=32 kN/m) by 120 cm?
Anit [1.1K]

Answer:

the work done by the linear spring will be equal to 23.04 k J

Explanation:

given,

k = 32 k N /m

deflected spring = 120 cm

                            = 1.2 m

work done by spring can be calculate as

                          = \dfrac{1}{2}kx^2

                          = \dfrac{1}{2}\times 32 \times 1.2^2

                          = 23.04 k J

hence, the work done by the linear spring will be equal to 23.04 k J

What is 220 C in degrees Fahrenheit (F)?
8_murik_8 [283]

Answer:

428°F

Explanation:

The equation to convert degrees Celsius to degrees fahrenheit is

°F (degrees fahrenheit) = (9/5 * °C (degrees celsius) ) + 32

°F = (9/5 * 220 °C (degrees celsius)) +32 = 428 °F (degrees fahrenheit)
