Calculate the energy stored in a spring when it is compressed 5mm by a 60n force

Answers

If a 60-N force is compressing the spring a distance of 5 mm = 0.005 m, then by Hooke's law, the spring has constant k such that

60 N = k (0.005 m)   ⇒   k = 12,000 N/m

Then the spring is storing

1/2 (12,000 N/m) (0.005 m)² = 0.15 J

Sketch the solid whose volume is given by the iterated integral.

Answers

A sketch of the solid whose volume is given by the iterated integral is shown in the image attached below.

How to calculate an integral?

In this exercise, you're required to sketch the solid whose volume is given by the iterated integral below. Thus, we would first of all evaluate the integral so as to get a unit value.

Given the following integral:

∫¹₀∫₀¹(4 - x - 2y)dxdy

Integrating x with respect to y, we have:

∫¹₀∫₀¹(4 - x - 2y)dxdy = ∫¹₀[(4 - (1/2)- 2y)]dy

∫¹₀∫₀¹(4 - x - 2y)dxdy = 4y - (y/2) - (2y²/2)|¹₀

Evaluating the integral, we have:

∫¹₀∫₀¹(4 - x - 2y)dxdy = 4(1) - (1/2) - (2(1)²/2)

∫¹₀∫₀¹(4 - x - 2y)dxdy = 4 - 1/2 - 1

∫¹₀∫₀¹(4 - x - 2y)dxdy = 5/2
