Types of Collisions - II01:19

Types of Collisions - II

8.0K
When two or more objects collide with each other, they can stick together to form one single composite object (after collision). The total mass of the object after the collision is the sum of the masses of the original objects, and it moves with a velocity dictated by the conservation of momentum. Although the system's total momentum remains constant, the kinetic energy decreases, and thus such a collision is an inelastic collision. Most of the collisions between objects in daily life are...

Elastic Collisions: Case Study

14.2K
Elastic collision of a system demands conservation of both momentum and kinetic energy. To solve problems involving one-dimensional elastic collisions between two objects, the equations for conservation of momentum and conservation of internal kinetic energy can be used. For the two objects, the sum of momentum before the collision equals the total momentum after the collision. An elastic collision conserves internal kinetic energy, and so the sum of kinetic energies before the collision equals...

Elastic Collisions: Introduction

13.0K
An elastic collision is one that conserves both internal kinetic energy and momentum. Internal kinetic energy is the sum of the kinetic energies of the objects in a system. Truly elastic collisions can only be achieved with subatomic particles, such as electrons striking nuclei. Macroscopic collisions can be very nearly, but not quite, elastic, as some kinetic energy is always converted into other forms of energy such as heat transfer due to friction and sound. An example of a nearly...

Types Of Collisions - I

7.4K
When two objects come in direct contact with each other, it is called a collision. During a collision, two or more objects exert forces on each other in a relatively short amount of time. A collision can be categorized as either an elastic or inelastic collision. If two or more objects approach each other, collide and then bounce off, moving away from each other with the same relative speed at which they approached each other, the total kinetic energy of the system is said to be conserved. This...

Collisions in Multiple Dimensions: Introduction

5.5K
It is far more common for collisions to occur in two dimensions; that is, the initial velocity vectors are neither parallel nor antiparallel to each other. Let's see what complications arise from this. The first idea is that momentum is a vector. Like all vectors, it can be expressed as a sum of perpendicular components (usually, though not always, an x-component and a y-component, and a z-component if necessary). Thus, when the statement of conservation of momentum is written for a...

Zones of Protection01:16

Zones of Protection

In power systems, the entire setup is divided into protective zones to isolate faults and protect the rest of the network. These zones include generators, transformers, buses, transmission lines, distribution lines, and motors. Each zone can be visualized as a separate room in a house, with each room protected by its own circuit breaker.
Protective zones are defined by closed dashed lines, containing one or more components. A key characteristic of these zones is the strategic placement of...

Area of Science:

  • Urology
  • Gastroenterology
  • Surgical Innovation

Background:

  • A 75-year-old male presented with lower urinary tract symptoms (LUTS) and a history of transurethral resection of the prostate (TURP) and laparoscopic inguinal hernia repair.
  • He had a bladder stone and obstructive prostate symptoms.

Observation:

  • During re-do TURP and stone removal, a ProTack staple from a prior hernia repair was found adhered to the bladder wall, acting as a nidus for stone formation.
  • The patient initially improved but later developed spontaneous intestinal obstruction, suspected to be from adhesions caused by other migrated tacks.

Findings:

  • A detached ProTack staple from hernia surgery migrated to the bladder, causing stone formation and LUTS.
  • The migrated staple necessitated surgical intervention, and subsequent intestinal obstruction was attributed to adhesions from other tacks.

Implications:

  • This case underscores the potential for rare, delayed complications from metallic hernia staples, including urological and gastrointestinal issues.
  • Clinicians should maintain awareness of long-term risks associated with surgical mesh and metallic implants, particularly concerning organ migration and adhesion formation.
