AI Thread Summary
To determine the load on the piers supporting a 700N girder, the problem involves calculating the forces acting on the girder based on its weight and the distances from the supports. The girder is 3.0m long, with supports located 30cm and 60cm from each end. The total weight of the girder must be balanced by the reactions at the piers, requiring the application of torque equilibrium principles. The discussion emphasizes the importance of showing work and explaining difficulties in solving the problem. Clear calculations and a structured approach are essential for finding the load carried by each pier.

A uniform girder weighing 700N is 3.0m long. It is placed horizontally on top of two narrow piers which is support it at points 30cm and 60cm respectively from its ends. Find the load carried by each pier.

Thread '1:1 versus 2:1 Mechanical Advantage debate'

The rope is tied into the person (the load of 200 pounds) and the rope goes up from the person to a fixed pulley and back down to his hands. He hauls the rope to suspend himself in the air. What is the mechanical advantage of the system? The person will indeed only have to lift half of his body weight (roughly 100 pounds) because he now lessened the load by that same amount. This APPEARS to be a 2:1 because he can hold himself with half the force, but my question is: is that mechanical...

Thread 'average velocity as a weighted mean'

Hello everyone, Consider the problem in which a car is told to travel at 30 km/h for L kilometers and then at 60 km/h for another L kilometers. Next, you are asked to determine the average speed. My question is: although we know that the average speed in this case is the harmonic mean of the two speeds, is it also possible to state that the average speed over this 2L-kilometer stretch can be obtained as a weighted average of the two speeds? Best regards, DaTario

Thread 'Newton's first law?'

Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?
