How did I study the physics of bending tubes?How did I study the physics of bending tubes?I also studied the physics of bending tubes and developed a computer program to predict the stresses, strains, wall thickness, and springback of a tube after bending. The computer model also estimates the force and torque required to bend tubes to a given radius.Tube Bending - Real World Physics Problems(pipe) Tube Bending - Real World Physics Problems

To control the axial tube motion, the pressure die applies axial force to the tube either through friction (between pressure die and tube) or through an optional boost block (as shown), which pushes against the back of the tube during bending. The role of the pressure die is two-fold.(pipe) What do you need to know about bending a pipe?What do you need to know about bending a pipe?Bending starts with knowing the properties of the tube or pipe youre working with.

The process of minimizing an impact force can be approached from the definition of the impulse of force . If an impact stops a moving object, then the change in momentum is a fixed quantity, and extending the time of the collision will decrease the time average of the impact force by the same factor. This principle is applied in many common-sense situations:
