Front View Definitions. Point: The edge and the spine meet at the point of the knife, which is often used for piercing. Tip: The front part of the blade that includes the tip. The tip is used for fine detail work. Swedge: This is a tapered or beveled false edge near the spine of the blade.It reduces thickness to improve piercing. Edge: The sharpened part of the …

A jack-knife accident is caused when the wheels of the trailer start to skin and the trailer begins to move faster than the cab. There are several factors that can cause a tractor trailer to jack-knife. Slippery wet or icy roads are the most common culprits in jack-knife accidents. The loss of traction can cause the trailer to slide out in one ...

What does 'jackknife a truck' mean? Jackknife truck and trailer are very common in the USA. Jackknife is a common phrase used for the phenomenon when the back trailer of a semi-truck and its cab move independently to each other. Because of this phenomenon, jack knife accidents occur. Been in a jack knife accident?

Nonetheless, in many cases the estimation of these factors can be highly subjective. A more advanced technique is proposed by Knights [7] through the Jack knife diagram (JKD), a logarithmic scatter plot that involves simultaneously three performance indicators: frequency, downtime, and unavailability. Using JKD, it is possible to classify ...

From there, we consider Pareto and Jack knife diagrams (JKD), which justify the introduction of the so-called cost scatter diagrams (CSD). An extended case study from a previous reference is used to illustrate the advantages of the new technique. Discussion and future work is presented in Section 4.

The jackknife position provides visibility of the anorectal area, so it is commonly used during proctologic procedures, including anorectal and colorectal surgeries (e.g., abdominoperineal resection, when parts of the colon, rectum, and anal sphincter are removed).The jackknife position also allows …

(DMG) (Labib, 2004) and the Jack-Knife Diagram (JKD) (Knights, 2001) can work together to address this issue. Maintenance costs and downtime depend on two factors: downtime frequency and downtime length or Mean Time To Repair (MTTR). Pareto histograms, traditionally used to prioritise failure codes, consider only one downtime criterion ...

Unlike the basic Jack-knife diagram, in which costs are not displayed as they are considered intrinsic based on their proportionality to the number and frequency of downtimes, this cost-scatter plot considers the two main criteria of interest-availability and cost-for spare part management [2,21].
