PHYSICS - physical pendulum - Need your help

AI Thread Summary
The discussion focuses on a physical pendulum modeled as a uniform rod with a length of 1.5 meters and a mass of 5 kg, pivoted at one end. Participants are asked to calculate the period of the oscillator, the angular displacement function θ(t), the angular kinetic energy after 1 second, and the maximum torque during oscillation. The initial conditions include an angle of θ0 = 0.2 rad and an instantaneous angular velocity of -0.5 rad/sec. Contributors emphasize using initial kinetic energy and energy conservation principles to derive the necessary equations. The thread encourages showing work for clarity and to facilitate assistance.

A physical pendulum consists of a uniform rod of length L = 1.5 meters. The mass of the rod is 5kg and the rod is pivoted about its end. The rod is pulled out to an angle of θ0=0.2rad and is then given a push so that its instantaneous angular velocity is -0.5 rad/sec.
a) What is the period of the oscillator?
b) Determine the function for θ(t), the angular displacement from vertical as a function of time.
c) What is the angular kinetic energy of the rod after 1.0 sec?
d) What is the maximum torque on the rod during the course of its oscillation?

Will you show your works so that it might be easy to help. The basic thing to start with is initial kinetic energy and then use energy conservatin to relate it to find other things. Specific helps will be given only after you show that you tried it.
 

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
