Applications Of Differential Equations
The radial stress p at distance r for the axis of the thick cylinder subjected to internal pressure is given by p + r (dp/dr) = A − p where A is a constant. If p = p0 at the inner wall r = r1 and is negligible (p = 0) at the outer wall r = r2 find an expression for p.

physics
a soccer ball with mass 0.420 kg is initially moving with speed 2.00 m/s. a soccer player kicks the ball, exerting a constant force of magnitude 40.0 N in the same direction as the ball's motion. over what distance must the player's foot be in contact with the ball to increase the ball's speed to 6.00 m/s?

Tension and stress of a chain lifting a beam
The 5m uniform steel beam has a mass of 600 kg and is to be lifted from the ring at B with the two chains, AB of length 3m., and CB of length 4m. a.)Determine the tension T in chain AB when the beam is clear of the platform. b.) stress if the cross-sectional area is limited to 500 mm2.

The Chain Rule Explained: Don't Just Memorize, Visualize It
Many students struggle with the Chain Rule because they get lost in the notation of f(g(x)) and dy/dx = (dy/du) * (du/dx). Let's break down what it actually means in plain English.
Design a rod and beam,with given stresses.
Hello all guys ! Can somebody please explain me how to solve this problem,i got exam which is coming closer and closer with every single day.Probably the problem will be easy for you,but I am new to this science (3-th semester in uni,and this things are new to me)So here is the task,from the exam.
