    Ball Force Wall
AI Thread Summary
To determine the force exerted by a ball against a wall supported by a thin wire, Newton's first law can be applied since the ball is not accelerating. The ball, weighing 42 kg and with a diameter of 32 cm, creates a scenario where the center of mass is 16 cm from the wall. A free body diagram is essential for visualizing the forces at play, particularly in forming a triangle with dimensions of 16 cm, 43.1 cm, and 46 cm. The geometry of the setup must be considered to accurately calculate the force. Understanding these principles will lead to the correct application of the necessary equations to solve the problem.

Hi,
I am having trouble figuring out how to start this problem, I have a free body diagram, but I am not sure which equation to use to help me solve for this, please help!

A solid form 42 kg ball of diameter 32 cm is supported against a vertical frictionless wall using a thin 30cm wire of negligible mass, how hard does the ball push against the wall?

Thank you!

The ball is not accelerating so you can use Newton's first law (sum of the forces = 0).
 
yes, but the center of the ball (where the mass is to be assumed) is 16cm away from the wall. so you have a triangle that is a=16 b=43.1 c=46, don't you ave to take that into account?

Thread 'Is 'Velocity of Transport' a Recognized Term in English Mechanics Literature?'

Here are two fragments from Banach's monograph in Mechanics I have never seen the term <<velocity of transport>> in English texts. Actually I have never seen this term being named somehow in English. This term has a name in Russian books. I looked through the original Banach's text in Polish and there is a Polish name for this term. It is a little bit surprising that the Polish name differs from the Russian one and also differs from this English translation. My question is: Is there...

Thread 'Beam on an inclined plane'

Hello! I have a question regarding a beam on an inclined plane. I was considering a beam resting on two supports attached to an inclined plane. I was almost sure that the lower support must be more loaded. My imagination about this problem is shown in the picture below. Here is how I wrote the condition of equilibrium forces: $$ \begin{cases} F_{g\parallel}=F_{t1}+F_{t2}, \\ F_{g\perp}=F_{r1}+F_{r2} \end{cases}. $$ On the other hand...
