The Problem The single pendulunm Consider the single pendulum shown below. There is a bob at the end of the pendulum, of mass For small oscillations in the case of a frictionless pivot and a rod with negligible mass, the motion of the pendulum over time can be described by the second-order linear ODE where θ is the angle between the rod and the vertical, g is gravity, t is the length of the rod and θ dag /dt2 Q1...

(38pt) Practice power expansion and initial condition A block of mass M is free to slide on a horizontal bar without any friction. A mass m is attached to the bottom of the block with a massless rod of length 1 and can oscillate freely in the same plane as the horizontal bar. (a) (5pt) Write down the Lagrangian of the...
A Pendulum with air resistance Pendula are widely used in applications including accelerometers and seismometers and are a model system to study vibrations and damping. Consider a pendulum comprising a small mass m that is connected by a thin massless rod of length l to a hinged support The hinge is frictionless but the mass experiences air resistance as it swings. The air drag force on the mass is Fdrag-kv |v, where v is the velocity of the mass and...
AP1. Consider the pendulum system shown below, where L = 0.7 meters, m = 1.5 kg, g = 9.81 m/s and e(t) is measured in radians. Pivot point Massless rod ! Lom, mass a.

Frictionless plane M 1.) Consider the coupled system shown at the right. The mass M is free to slide on a frictionless surface and is connected to the wall with a spring of spring constant k. Mass M2 is 2000 attached to My with taut rope of length (it acts as a pendulum). The vertical line shows the equilibrium position when the spring is un- stretched (r = 0).
