Ex 1.21 The dumbbell

…

Consider two massive particles in the plane constrained by a massless rigid rod to remain a distance l apart, as in figure 1.5.

…

a. Write Newton’s equations for the balance of forces for the four rectangular coordinates of the two particles, given that the scalar tension in the rod is F.

~~~

[guess]

\displaystyle{m_0 \ddot y_0 = F \sin \theta}

\displaystyle{m_0 \ddot x_0 = F \cos \theta}

\displaystyle{m_1 \ddot y_1 = - F \sin \theta}

\displaystyle{m_1 \ddot x_1 = - F \cos \theta}

[guess]
