Hello friends...
I have an small antenna( irregular shape) , mass about 1.5 Kg (about CG), the moment of ineria about spinning axes(Iyy) is 0.0255kg.m^2. product of inertia also known (Ixy, Iyz, Ixz).
Required angular velocity (w) = 50 deg/sec
angular acceleration (a) = 400 deg/sec^2
The rotation axes is 3mm away from the CG of the antenna. If want to rotate the antenna in the both the direction for every 1hr. How to find the torque and power requirement to rotate it.
Please any suggestions...


Thanks in advance

.To find the torque required to rotate the antenna, you will need to calculate the angular momentum of the antenna. This can be done by multiplying the angular velocity (w) and the moment of inertia (Iyy). The angular momentum is then equal to the product of the torque and the angular acceleration (a). The power required to rotate the antenna can then be calculated by multiplying the torque and the angular velocity (w).
 

Thread 'Initial conditions for orbits around a wormhole'

Hi, I had an exam and I completely messed up a problem. Especially one part which was necessary for the rest of the problem. Basically, I have a wormhole metric: $$(ds)^2 = -(dt)^2 + (dr)^2 + (r^2 + b^2)( (d\theta)^2 + sin^2 \theta (d\phi)^2 )$$ Where ##b=1## with an orbit only in the equatorial plane. We also know from the question that the orbit must satisfy this relationship: $$\varepsilon = \frac{1}{2} (\frac{dr}{d\tau})^2 + V_{eff}(r)$$ Ultimately, I was tasked to find the initial...

Thread 'Help to convert units of a simple formula'

The value of H equals ## 10^{3}## in natural units, According to : https://en.wikipedia.org/wiki/Natural_units, ## t \sim 10^{-21} sec = 10^{21} Hz ##, and since ## \text{GeV} \sim 10^{24} \text{Hz } ##, ## GeV \sim 10^{24} \times 10^{-21} = 10^3 ## in natural units. So is this conversion correct? Also in the above formula, can I convert H to that natural units , since it’s a constant, while keeping k in Hz ?
