Learning Goal: To set up and analyze equations of motion in a cylindrical coordinate system. The mechanism shown in the figure below rotates about the vertical axis. The collar has a mass m = 3.3 kg. The spring has an unstretched length of 445 mm and the spring constant is k = 210 N/m. The distance d = 275 mm, and the collar is required to stay a fixed distance r = 660 mm from the vertical axis. C- The maximum allowable angular velocity when there is friction Consider the same mechanism again, with m = 3.3 kg, d = 275 mm, k = 210 N/m, and μs = 0.62. What is the maximum angular velocity allowable if the collar is to remain at a constant distance r = 660 mm from the axis of rotation? Express your answer to three significant figures.

Consider the simple pendulum free body diagram, as shown in Figure 1b. When displaced by angle ̈θ, the component of the force of gravity on the mass, m, acts to pull the pendulum back toward vertical equilibrium, such that: Fnet = ma = -mgsinθ This second order differential equation has the familiar form describing simple harmonic motion. So, substituting in a solution of θ(t) = Asin(ωt + ϕ), we can show that: d²θ/dt² + (g/L)θ = 0 where L is the length of the pendulum and g is the acceleration due to gravity. This equation leads to a simple expression for the period, T. Before your lab session, provide a full derivation of ω and convert it to T, which you can use in your calculations.

The equation for the motion of a pendulum, shown in Figure 1.19, is derived by considering Newton's law of motion. Since the body of mass m is restricted to move in a circle with radius l, the force on the body in the radial direction must balance. If T is the tension in the rod supporting the weight, then T = mgcos(̘) where ̘ is the angle in radians. The acceleration in the angular direction is driven by the tangential force. For a mass m, we have d²̘(t)/dt² = -mg sin(̘). This is an example of a nonlinear differential equation because ̘ appears in the argument of the function sin(̘). Special methods must be used to solve this equation, which are discussed in Chapter 5. Instead, we will restrict the pendulum to cases where the deflection is small. In other words, ̘(t) is always small, and we approximate sin(̘(t)) ≈ ̘(t). Thus, the linearized version of the differential equation is d²̘(t)/dt² + (g/l)̘(t) = 0.

00:01 We'd like to find the max angular velocity allowable.
00:04 So let's find our stretched length.
00:07 Our stretched length, capital l, is equal to d squared plus r squared.
00:12 So we plug in our 275 millimeters squared plus 660 squared to get 715 millimeters.
00:23 And our m -u -s is equal to 0 .62...
