Consider the pipe segment $AB$ that lies in the $xz-$ plane. The pipe is bent in a circular form with a

radius of $4\mathrm{.}8m.$ The pipe is supported at $A$ by an unknown support and at $B$ with a cable $BC.$

The system is subjected to a loading that is NOT shown.

Let $F$ denote the tension in cable $BC$ and consider the force $\frac{?}{\text{b}\text{a}\text{r}}(F)$ as in the sketch that the cable

exerts on the point $B$ of the pipe.

Answer the following questions.

a$)$

Calculate cartesian vector moment $\frac{?}{\text{b}\text{a}\text{r}}(M)$ of force $\frac{?}{\text{b}\text{a}\text{r}}(F)$ about point $A.$

$\frac{?}{\text{b}\text{a}\text{r}}(M)=1\frac{,}{b}ar(i)\frac{+}{b}ar(j)\frac{+}{b}ar(k)$

b$)$

The geometrical representation of $\frac{?}{\text{b}\text{a}\text{r}}(M)$ is a vector that lies on a line. say $l.$

Complete the statements below by selecting the correct cption from the dropdown list.

Statements:

The point $\frac{?}{?}$ points

lies $f$ lie on $l.$

Vector $\frac{?}{\text{b}\text{a}\text{r}}(M)$ is $[$

to $l.$

The moment axis is

to $\frac{?}{\text{b}\text{a}\text{r}}(AB).$

$\frac{?}{\text{b}\text{a}\text{r}}(BC)$ is

$\frac{{?}_{10}}{b}ar(M)$

The rotational effect that develops about $l$ is

as perceived from the tp of the

$\frac{?}{\text{b}\text{a}\text{r}}(M)=$ vector.
