What disadvantages does a conveyor belt have?

1. Belt Conveyor System

Advantages

One of the cheapest conveyors

Simple and easy to use

Can have changes in elevation

Can be loaded from any place along the belt

Disadvantages

The simplicity means very limited features

Belt can be difficult to clean and generally does not leave a very successful result

Sticky material can get stuck on the belt and transfer to the return side, the rolls, idlers and pulleys

2. Roller Conveyor System

Advantages

Can use gravity for moving the product on a decline angle

No power means less cost and more environmentally friendly

Quite modular andcan be utilized in many ways

Fairly low maintenance

Disadvantages

Products may end up being damaged when moved by gravity

Heavy and therefore not very portable

No control of conveyor speed

3. Powered Roller Conveyor System

Advantages

Effective horizontal transportation over a longer distance

The speed and also the process can be easily controlled and the risk for damage is reduced as the parts never touch

The small zones of the system are powered independently and can be set up to run only when an item is present

If a motor breaks down, it will only stop one zone

Disadvantages

Noisier than many other conveyors

More expensive than other conveyors

Not as flexible with what type of items it can handle

4. Overhead Conveyor System

Advantages

Can utilize the space overhead maximizing the full capacity of a facility

Buffer stores of serial produced components can be stored and sequentially delivered to a pick point when required

Full production systems can be created in a friction drive overhead conveyor using multi drive technology offering speed differentials

Lower operating costs and known for being very safe

Disadvantages

Generally more expensive than a floor based conveyor system

If breaking down, it can be more challenging to repair if no foresight at the planning stage and installation for maintenance

If chain based, it tends to need continual lubrication meaning grease or oil might drop from the system

As you can see, there are pros and cons for each conveyor system. One of the most important things to consider is therefore your specific business and the type of material you wish to transport. Some of the material’s characteristics to consider are size, weight, and density. But key considerations should also be the size of the system compared to the size of your facility as well as the environment itself – temperature, humidity and vibration for example. Feel free to contact us and we’ll help you determine any potential risks and possible countermeasures in order to create the safest and most effective environment.

Explanation:

object 2 because all the other ones are wrong

russian is not my first language, so i'm afraid i can't write out an answer in russian, but hopefully you can find a way to do so. here's my best translation of the problem: you're given a plot of a particle's position in one-dimensional space over time, and you're asked to find either the total distance traveled by the particle after 6 seconds had elapsed, or the total displacement of the particle after 6 seconds.

if you want the total distance traveled, you would first need to determine the particle's velocity as a function of time, then integrate that over the 6-second interval. we know the position function is quadratic with roots at 0 and 6, so we have

where is unknown. because the position is parabolic, there is symmetry about the midpoint at , and we know that

so that the position function is

which means the velocity is

then the total distance traveled is

so the total distance traveled is 20 m.

on the other hand, if you want to find displacement: the particle starts at and ends at , so its displacement is 0.
