Physics Free Body Diagram Question

AI Thread Summary
To create a free body diagram for a block on a 30-degree inclined plane with friction, it is essential to accurately represent the forces acting on the block. The gravitational force acts downward, while the normal force is perpendicular to the surface of the incline. Friction opposes the potential motion of the block, which is directed down the slope due to gravity, indicating that friction must act up the incline. Since the block is stationary, the magnitude of the frictional force equals the component of gravitational force acting down the incline. Understanding these forces is crucial for accurately labeling the free body diagram.

Question:
Draw and label the free body diagram
of a block on a plane inclined 30Efrom the
horizontal. .There is friction and the block is
stationary The magnitudes of the
vectors must be correctly scaled and the
directions correct.
3.

The Attempt at a Solution



Draw 30 degree angle but I don't know how to factor in friction for this block. Please help with this free body diagram.

To determine the direction of friction, it is worth recalling that friction always acts in the opposite direction of the motion of the object. In which direction is the block "trying" to move? Also, the block is stationary: what does this tell you about the magnitude of friction?
 

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 'Collision of a bullet on a rod-string system: query'

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 hanging mass'

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...
