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

4) A steel tape is placed around the earth at the equator when the temperature is 0 C. What will the clearance between the tape
snow_lady [41]

Answer:

2102.1 m

Explanation:

Temperature at the equator = 0⁰

Radius of the earth = 6.37x10⁶

Required:

We how to find out what the clearance between tape and ground would be if temperature increases to 30 degrees.

Final temperature = ∆T = 303-273 = 30

S = 11x10^-6

The clearance R = Ro*S*∆T

=6.37x10⁶x 11x10^-6x30

= 2102.1m

Or 2.102 kilometers

Thank you
