A laparoscopic tool consists basically of a long, thin shaft with a gripper at the end. Its shaft is a hollow tube through which a wire is used to actuate the gripper. Derive a performance index for a light, stiff, thin-walled tube of this type under bending loads. Consider the diameter to be fixed and the tube thickness to be the free variable. [Hint: use the fact that this is a thin-walled tube to obtain a simplified moment of inertia expression for use in deriving the performance index.]

the correct answer is c.stops after infancy and childhood.

myelin is the substance of the central nervous system (cns) that insulates nerve cell axons to increase the speed at which nerve impulse travels. myelination is a process of myelin formation. this process occurs postnatally, begins in the embryo during the midst of early development and finishes after birth.

One of the benefits of working with chlorinated polyvinyl chloride (CPVC) pipe is that it can be cut with a variety of different tools that don’t require any electricity or heat. However, different cutting methods are preferred over others, depending on the application.

When cutting CPVC pipe, it is important to make a square, flat cut. An uneven cut limits the bonding area and weakens the fitting.

To help you make the best possible cut, we’ve put together the following dos and don’ts when cutting CPVC pipe in different situations.
