The simple pendulum is fully actuated. Given enough torque, we can produce any number of control solutions to stabilize the originally unstable fixed point at the top (such as designing a feedback controller to effectively invert gravity). The problem begins to get interesting (a.k.a. becomes underactuated) if we impose a torque-limit ...

Question 4: The frequency of the simple pendulum is 0.8 Hz. What is the gravity of a simple pendulum if the length of the pendulum is 2 m? Answer: Given that frequency of the simple pendulum (f)=0.8 Hz. Length of the simple pendulum (L) = 2 m. To find gravity of the simple pendulum we know that, T = 2 π √(L/g) We know that T=1/f. 1/f=2 π ...

Time Period of a Simple Pendulum. A simple pendulum consists of a string and a bob at the end. The bob is a weight, generally spherical and considered a point mass. The bob moves from side to side. The string is light and inextensible remaining in tension throughout the oscillations. The string is attached to a fixed point above the equilibrium position. The time …

The simple pendulum is another mechanical system that moves in an oscillatory motion. It consists of a point mass ' m' suspended by means of light inextensible string of length L from a fixed support as shown in Fig. 2.8.The motion occurs in a vertical plane and is driven by a gravitational force. The forces which are acting on the mass are shown in the figure.

It is clear that the approximation is quite good for small angles, and gets worse the larger your angle is (shocking result, given its name). This means that simplifying our differential equation to $$ frac{d^2theta}{dt^2}=omega_0^2theta $$ will act as a good approximation, as long as we keep the initial angular displacement of our pendulum fairly small.

The pendulum was released from (90) and its period was measured by filming the pendulum with a cell-phone camera and using the phone's built-in time. In order to minimize the uncertainty in the period, we measured the time for the pendulum to make (20) oscillations, and divided that time by (20). We repeated this measurement five times.

T is the period of oscillations - the time that it takes for the pendulum to complete one full back-and-forth movement; L is the length of the pendulum (of the string from which the mass is suspended); and; g is the acceleration of gravity. On Earth, this value is equal to 9.80665 m/s² — this is the default value in the simple pendulum ...

Compound Pendulum vs. Simple Pendulum What's the Difference? A compound pendulum and a simple pendulum are both types of pendulums used to measure time or oscillate. However, they differ in their construction and behavior. A simple pendulum consists of a mass (bob) attached to a string or rod, swinging back and forth in a straight line.
