NAME: our mersse Problem 1. (25%) The system shown below consists of a rotary two-disk pulley, a horizontally translating body with a spring and damper attached to it, and two massless rods (the...
Two masses are connected via a spring and a string over a massless pulley as shown below. The first mass has a mass, m1 = 4 kg, and the second, m2 = 3 kg. The inclined plane sits at an angle, θ = 30°, with a coefficient of static friction with the first mass, μs = 0.3. The spring has a spring constant, k = 4 N/m. How far past its natural length is the spring extended to keep the...
Exercises 1. (introduction) Sketch or plot the displacement of the mass in a mass-spring system for at least two periods for the case when Wn-2rad/s, 괴,-1mm, and eto =-v/5mm/s. 2. (introduction) The approximation sin θ ะ θ is reasonable for θ < 10°. If a pendulum of length 0.5m, has an initial position of 0()0, what is the maximum value of the initial angular velocity that can be given to the pendulum without violating this smll angle approximation? 3. (harmonic...
