Torque and netwon's second law: True or false question

AI Thread Summary
The discussion centers on the statement "Torque cannot exist without a force acting on the body," which is evaluated as true. The equation for torque, t = Frsin(theta), indicates that if the force (F) is zero, then torque (t) must also be zero. This reinforces the idea that a force is necessary for torque to exist. Participants agree that without a force, torque cannot be generated. The conclusion drawn is that the original statement is indeed true.

Homework Statement


True or false: "Torque cannot exist without a force acting on the body"


Homework Equations


t = force(rsin(theta))


The Attempt at a Solution


I can't find a reason to believe the statement is false. Look at the equation:
t = Frsin@, where the @ sin is theta, and F is force.

if F is 0, then t must equal zero, so I think the original statement, "Torque cannot exist without a force acting on the body" is true.

Sounds right to me.
 
Thread 'Collision of a bullet on a rod-string system: query'
In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
Thread 'A cylinder connected to a hanged 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...
