Answer:

a.) -147V

b.) -120V

c.) 51V

Explanation:

a.) Equation for potential difference is the integral of the electrical field from a to b for the voltage V_ba = V(b)-V(a).

b.) The problem becomes easier to solve if you draw out the circuit. Since potential at Q is 0, then Q is at ground. So voltage across V_MQ is the same as potential at V_M.

c.) Same process as part b. Draw out the circuit and you'll see that the potential a point V_N is the same as the voltage across V_NP added with the 2V from the other box.

Honestly, these things take practice to get used to. It's really hard to explain this.

public class calculate {

static float a=0,b=0;

double cal()

{

if(a==0||b==0)

{

System.out.println("no values found in a or b");

1. Reflect on the first case study where a robotic platform crushed a machine operator and generate ideas to prevent the occurre
Nikolay [14]

For question 1:

A typical sort of mishap in which a robot injures a worker. This can occur when the <u><em>robotic platform injures a worker</em></u>. These types of incidents should be avoided in the workplace. The control framework is taken to avoid these mishaps:

  • When work is protective gear like helmets and safety shoes should be used.
  • The robotic equipment should be kept separate from the regular working environment.
  • Robots should be employed for efficiency.
  • Workers are well trained in the use of safety equipment.
  • This sort of disaster might occur anywhere when safety precautions are not taken.

For question 2:

The common occurrence when an incident was caused by a robotic, this example is the robot strikes the mold setter head, which can result in dangerous occurrences.

  • It should be ensured that it does not happen again.
  • First and foremost, the dinosaur's work must be restricted to a certain region, and the job of other employees wouldn't be in direct opposition with the robot's work.
  • The robot is utilised for automation, whereas the workers are used in other tasks.
  • This should also be ensured that all workers wear a helmet, safety footwear, and other safety equipment while work.
  • There should be appropriate arrangements for first aid and medical facilities.

For question 3:

Once activated, the security toolkit will be able to identify the areas where adequate safety measures were not applied, and the further calculation can be defined as follows:

It will be able to trigger safety engine as well as on engineers to check into and <em><u>ensure proper safety disting to look into and guarantee the likelihood of an accident</u></em>:

  • strolling on the shop floor or on a building site without personal protection equipment standing beneath the possessive object ( like those done by cranes).
  • Scaffolding and ladders must be made of approved materials.
  • It can activate safety engines and on-site engineers to investigate and <em><u>guarantee adequate safety distinguishment to investigate and assure the possibility of an accident:</u></em>
  • strolling just on the shop floor or on a construction site while utilizing protective gear for protection sitting beneath the possessing object ( like those done by cranes).
  • <em>Scaffolds and platforms</em> must be made of approved materials.
  • <u>Slings, D-shackles, Bow Shackles, and Crane Hooks</u> must be examined on a regular basis by a third party since the utilized machinery at the site is just too old, welders must protect their <em><u>eyes with black glass</u></em>.

Control measures:

Begin any task with the good method statement, or what is written must be as follows:

  • The risk response strategy must be followed, but high-risk occurrences must be handled with care.
  • Third-party examination at regular loads, when operating on the <em><u>shop floor, aim to employ automated machinery</u></em>.
