Question B1 (this part is made of three short questions) (Topics assessed: EOM of a 1DOF rotational system, damped harmonic motion experimental data evaluation and analysis, modelling) 1. A uniform rod of mass m = 1 kg and length 1 = 0.25 m (Figure QB1.1) is supported by a pin joint at A and a spring with stiffness k = 300 N/m at B. The mass moment of inertia of the rod about point A is: ml...

For my lab a 50g mass is on a spring. The spring is pulled down
a different length for each trial and then released. What would the
amplitude of motion be for this experiment and how can I test that
the frequency is independent from the amplitude.
In cases where the restoring force is proportional to the amount of displacement from the oquilibrium position, the object undergoes simple harmonic motion (SHM). An object on a spring is the simplest example...

A damped system consists of a mass (m = 30kg) supported on a spring and a damper in parallel. In an experiment, the period of vibration of this system was measured to be 0.5 seconds, and the ratio of maximum displacement between two successive cycles was determined from the experimental data to be 20. Determine: a. The logarithmic decrement. [2] Q4a. Answer: b. The damping ratio, commenting if this is over-damped, critically damped, or under-damped. [4] Q4b. Answer: c. The...

A mass of 1.25 kg stretches a spring 0.06 m. The mass is in a medium that exerts a viscous resistance of 56 N when the mass has a velocity of 2 . The viscous resistance is proportional to the speed of the object. Suppose the object is displaced an additional 0.03 m and released. Find an function to express the object's displacement from the spring's equilibrium position, in m after t seconds. Let positive...
