Tractors are extremely important agricultural vehicles. These machines are ubiquitous across the globe and range from rather small lawn tractors to giant monster worth hundreds of thousands of dollars. However, most of them have something in common – their exhaust pipes are pointing straight up in front of the driver’s cab. Meanwhile exhaust pipes of cars are located at the back, typically at bottom of the vehicle. Why is that? We will discuss the reason behind the vertical exhaust in this article.
Following are the reason why tractors have vertical exhaust :
1) Tractor is a off-road vehicle, usually used in every terrain including water dominated areas, where, there are chances of water to get in exhaust pipe and causing harm to the engine and exhaust system itself.
2) Mounting the exhaust pipe in the front has an added cost advantage – that’s where the engine is and less pipework is required this way. Less pipework – less maintenance as well.
3) Many chemicals are spread on crops or plants by driving tractor on the space between plants. If exhaust system is horizontal and below the driver them harmful and hot emissions can harm the crop.
4.)A normal tractor is constituted of two major parts – it can be split in two, which is occasionally done to repair transmission. Having an exhaust running from front to back would make such repairs hardly possible or very difficult.
Special note - Sometimes the end of exhaust pipe is curved, or has a hinged cover flap which the gas flow blows out of the way, to try to prevent foreign objects (including droppings from a bird perching, rain drops, ice on the exhaust pipe when the vehicle is not being used) getting inside the exhaust pipe.

You might have wondered why does almost every motorcycle have its exhaust placed on the right, and not the left?It is not a design constraint as such and you can have the silencer on the left as well. But there could be many reasons otherwise.We will discuss these reasons in this article.
Manufacturers have just stuck to the design that was implemented on the very first internal combustion-powered, single-cylinder motorcycles.The first motorbike without pedal was having exhaust on the right side. Since then manufacturers decided to mount the exhaust on the right side of the motorcycle.
Apart from this other reasons that are important to consider are as follows:
1. The exhaust fumes would be a little farther from the pedestrain walking sidewalks on the left.
2. Lot of women and old people sit sideways and it is much more safer to disembark them to the left. Silencer to the right helps with that.
3. Usually, there's a chain sprocket on the left side and having the silencer on the right balances the mass to some extent.
4. The way we learn to ride a bike, usually the left foot comes off the foot rest first when we are braking to a stop. Having the silencer to the right minimizes the risk of the foot coming in the proximity to the hot exhaust pipes.
But,it need not to be necessarily on right . Sports bikes have both sides , some have under the seat. But in general the exhaust is placed on the right side for above reasons.
Sometimes when you buy a strip of medicine (tablets), you notice of empty slots. Irrespective of the exact shape of the tablet, it can be round, rectangle, oval; every strip is packaged in this typical design-geometry.We will understand the reason behind the empty slots in this article.
Reason 1:
To keep up the standard size of the packing boxes, the company adds these extra spaces to avoid the extra cost.
Reason 2:
Since these tablets are small in size, but the minimum information required to be given on them is quite a lot, so the overall size of packaging is generally large so as to accommodate all relevant information.
Reason 3:
These extra empty spaces help to avoid breakage and spilling of medicines during transportation. This is one of the most important reasons why these empty spaces are there.
Reason 4:
This is a tricky one where our mind would get fooled by the packing. Extra spaciousness gives a feel that the tablet is worth the cost. But the actual fact is that it does not cost even an extra penny for the special packing!
Reason 5:
Empty space left is to increase the inertness of the tablet by pumping vacuum or inert gases inside the empty space. If air is present inside the empty space, then the tablets might get oxidized resulting in poor performance of the medicine.
Hope,this article might have helped you to understand the logic behiend those empty space.
