The discussion revolves around the forces acting on a winch system, particularly focusing on the differences between ideal and real winches, and the implications of these differences on force calculations. Participants are examining the tension in the rope and the forces acting on the drum/axle, questioning why certain forces are acting in specific directions and how they relate to the overall system dynamics.
The discussion is ongoing, with participants exploring various interpretations of the forces involved. Some have provided insights into the mechanical advantage of the winch and the relationship between torque and angular velocity, while others are seeking clarification on the underlying principles and assumptions being made.
Participants are grappling with the implications of a system in equilibrium and the necessity of balancing forces and torques. There is a focus on understanding the role of friction and the conditions under which the forces sum to zero.
is work done as friction. what exactly would be the wasted energy here?CWatters said:
if it's the reaction of 180N, won't it be on the axle itself, but how does the trailer exert this force. the axle is in the air?CWatters said:
another thing. by calculation, i went as follows, Tx0.08 = 180x0.4 giving T = 900NCWatters said:
The vertical supports holding the axle are part of the trailer. If the axle is to remain in place, there must be a horizontal force to the left balancing the sum of horizontal forces to the right.PhysicStud01 said:
That's the tension in the rope.PhysicStud01 said:
The winch's handle length vs. drum radius offer a mechanical advantage. A narrower drum means the handle will be easier for you to turn, but you'll have to turn it more times to draw in the same length of rope.
yeah, but why equate the moment. shoudl there be a resultant moment, for the drum to rotateNascentOxygen said:
