What Is the Kinetic Energy Equation for a Mass on a Double Pendulum?

AI Thread Summary
The discussion focuses on finding the kinetic energy equation for a mass on a double pendulum, specifically considering the effects of torque on the main bar. The user seeks clarification on how to calculate the position and angles of the mass based on given torque and other parameters. There is mention of using the equation K = 1/2*I*w^2, but confusion arises regarding the calculation of angular velocity (omega). The conversation also touches on the user's background in calculus and their interest in applying this knowledge to a personal project. Overall, the thread highlights the complexities of modeling a double pendulum system in terms of kinetic energy and motion.

You can treat the cable as another rigid bar in this case, both massless. I just need the equation for the Kinetic Energy of the mass on the end.

Is there an equation for if the main bar is torqued at a given τ(t), and any other necessary information is given, to find the position of the mass on the end or the angles of the two bars at any given time?

I'm in a Statics class right now and will be taking advanced dynamics in the fall but I'd like to work on a personal project in the fall. Done through Calc 4 and Stokes Theorem if it matters.

Thanks

Burn the thread. The ball will remain and will perform free fall. Then you will easily get your answer.
 
That doesn't help at all.

I know K = 1/2*I*w^2 but what would the omega be? Just both angular velocities added together?
 
Sorry, misunderstanding. Please delete this post.

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
