There are many like flexible coupling, jaw coupling, sleeve coupling, tire coupling, pin and bush coupling, rigid coupling, etc

A good quality education is one that provides all learners with capabilities they require to become economically productive, develop sustainable livelihoods, contribute to peaceful and democratic societies and enhance individual well-being.

as logically as i can solve it, here is the solution x + 3x + 60 = 180 4x + 60 = 180 4x = 180 - 60 4x = 120 4x/4 = 120/4 x = 30 thus angle 1 = 30 degrees, angle 2 = 60 degrees, and angle 3 = 90 degrees hope this helps. in my equation, the x is angle 1 and the 3x (because it is three times as large as angle 1) is angle 3, and the 60 is angle 2. all angles in a triangle must total 180 degrees, so this equation is legitimate, and the solution is correct.

mercury in tube strain gage.

I guess it depends on whether it's sealed or not.

If it's open to the atmosphere how can it be under pressure ?

If it's sealed it could be put under (positive or negative) pressure so would be, by definition, a pressure vessel IMHO.

It is difficult from cleaning point of view. Both end chambers have to be removed so as to clean the heat exchanger with odd nos of passes.

Thanks & Regards

First we need to convert 30 seconds in hour or convert the constant speed in m/s. I convert 30 second in hour; 30s=0.083h V=d/t. d=v.t d=72km/h.(0.0083) d=0.6km II convert 72km/h in m/s calculate the distance v=72km/h .(1000m/3600s), so 72km/h=20m/s we can calculate the distance v=d/t, so d=v.t d=20m/s.(30) d=600m or 0.6km

Blanking and punching are both shearing operation. The difference is only in the scrap. In blanking what you cut out is of interest.
In punching what you cut from is of interest.


For example: You cut a hole in a sheet metal. If you are interested in the disc that is cut out, then the process is called blanking. The sheet metal with a hole through it is the scrap. If you are interested in the sheet metal that now has a hole through it, then the process is called punching. The disc is the scrap.

find the strength of the member subject to bending or shear. Moment of inertia is used to find radius of gyratia or flexural regidity so that member strength flexural stress is found

The distance of Kevin's drive is a function of the torque of his swing.

The most familiar example is the rotary solenoid, an electromechanical device that rotates similar to a motor but makes only a partial revolution. After completing its rotation it must return to its original position either by a return spring or under electrical power. Try searching under the name of its inventor, George H. Leland, for much more information.

Find a design pattern online for a hand screw press and follow it or alter it as needed to fit your needs.

A solenoid will never become an electrical generator. The two articles in the question are two different devices. A solenoid, is usually associated with an electrically operated valve. An electrical generator is used to produced a voltage output of a specific value and an amperage of a specific value. Combined amps and volts results in a wattage output. It is the wattage rating that generators are sized by.

In a pipe line or vessel if vertically placed and two pressure gauges mounted in top and bottom places of the pipe line and the internal pressure will very. Top mounted pressure gauge is lower than the bottom mounted pressure gauge. The Pressure will change due to the height variation's. The Internel fluid height acting additional pressure . so that the pressure difference in two gauges located in different heights.

Assuming the generator is in good condition and designed to be connected to a power grid. A generator can be connected by ensuring the generator is at very nearly the same speed as the grid (typically very slightly faster) and is generating a similar voltage. When the phases of the generator and grid align, the circuit breakers can be closed and the generator will become locked to the grid. If the generator is connected to the grid without being in phase, the difference in phase will allow significant current to flow and in some situations can actually be worse than a direct short circuit. As a result of this power companies use sophisticated equipment to ensure that generators can be safely connected to the grid without damage.

Household, camping and most industrial generators are not designed to be synchronised with the grid and should not be connected to a grid system.

Diameter is equivalent to the width of a circular object. Width is the shorter side of a non-circular two-dimensional object. The longer side is considered the length.

Check the shielding gas & its flow rate.

The 'J' has to do with the heat treatment of the material, and the 55 is the minimum yield strength (MYS) of the material is ksi (or thousand psi)

becuz it was better for docking near the coastal area known as 'land'

LOL XD

SEE YAL LATER LOL ;D <3

Someone who operates sound generating equipment, such as equalizers, amps, and synthesizers.

Something is loose and/or vibrating. The cutting tip may be too long, ie, it may be too far from the mounting assembly, there could be a problem with the bearings, or the speed could be too high.

The excitation system puts the load on the generator, so if it fails, the generator is liable to overspeed.

Think of it as the gears on a bicycle, where your legs are the power source, the gearing is the excitation system. If you're riding along, and suddenly your gears fall off, your legs will start to move very fast. You might hyper extend your knee, your foot might slip off the medal, you could hurt yourself in a bunch of different ways because you expect the resistance to be there and it is suddenly gone. The same applies to a generator - it's designed to run at specific speeds. Going significantly faster can cause all kinds of problems.
