Question
A differential element taken from a curved bar is shown in the figure. Show that $d N / d \theta=V, d V / d \theta=-N$ $d M / d \theta=-T,$ and $d T / d \theta=M$
Step 1
For the equilibrium of forces in the x and y directions, we have the following equations: \[ \begin{align*} N \cos \frac{d\theta}{2} + V \sin \frac{d\theta}{2} - N - dN \cos \frac{d\theta}{2} - V - dV \sin \frac{d\theta}{2} &= 0 \quad \text{(1)} \\ N \sin Show more…

Determine the system equation of motion in terms of the variable $\theta$ shown in the figure. Assume small angular motion of bar $O A,$ and neglect the mass of $\operatorname{link} C D$
Let $F$ makes an angle $\theta$ with the horizontal at any instant of time (Fig.). Newton's second law in projection form along the direction of the force, gives: $F=k m g \cos \theta+m g \sin \theta$ (because there is no acceleration of the body.) As $\vec{F} \uparrow \uparrow d \vec{r}$ the differential work $d A=\vec{F} \cdot d \vec{r}=F d s$, (where $=k m g d s(\cos \theta)+m g d s$ $k m g d x+m g d y$ Hence, $=k m g l+m g h=m g(k l+h)$

Consider a rapidly spinning gyroscope whose axis is precessing uniformly in a horizontal circle of radius $r,$ as shown in Fig. 11.10 Apply $\vec{\tau}=d \vec{L} / d t$ to show that the angular speed of precession about the vertical axis through the center of the circle is $m g r / L$.
