Chapter 5: Q28P (page 257)

In Problems 17 to 30, for the curve $y = \sqrt{x}$ , between $x = 0$ and $x = 2$ , find:
The mass of a wire bent in the shape of the arc if its density (mass per unit length) is.

Short Answer

Expert verified

The mass of a wire bent in the shape of the arc is $\frac{13}{6}$ .

Step by step solution

Definition of Mass

A physical body's mass is the amount of matter it contains. It is also a measure of the body's inertia, or resistance to acceleration (velocity change) when a net force is applied.

Determination of the Mass of the wire

Calculate the mass of the wire.

$M = \int λ d s = \int_{0}^{2} \sqrt{x} \sqrt{1 + y^{c 2}} d x = \int_{0}^{2} \sqrt{x} \sqrt{1 + \frac{1}{4 x}} d x = \int_{0}^{2} \sqrt{x + \frac{1}{4} d (x + \frac{1}{4})} = \frac{2}{3} {(x + \frac{1}{4})}^{3 / 2} = \frac{2}{3} [\frac{27}{8} - \frac{1}{8}] = \frac{13}{6}$

Thus, the mass of the bent wire is

\frac{13}{6}
