What do hydraulic presses make?
The difficulty in answering this question is that there are used in an enormous number of manufacturing operations. So, any of the things that can be made using any of the following procedures could involve the use of hydraulic presses:
- clinching or rivetting
- forging
- moulding
- punching
- extruding
Related equipment can be used for hydroforming.
What will do first before using a new type of vernier scale?
There are several things that you should do first before using a new type of Vernier caliper. You should ensure that you fully understand how it works and test it elsewhere before using it in the real project.
You want topics of recent trends in electronics for doing paper presentation at engineering level?
can u tell some recent topics in giving the prfesentation in the college related to computer techniques that is recently work..
so that i wl get gud response by college and will help in my placment..
Is Power required to drive a centrifugal pump is directly proportional to diameter of the impellor?
yes....power is directly proportional to cube of dia.
What are the Cutting tools on Lathe machine?
Now a days verities of materials are using for making lathe cutting tools. In earlier days Hardened high carbon steelswere used. High Speed Steel (HSS) came next to HCS. Ordinary carbide inserts of different grades came after HSS. Coated carbide inserts of various grades suitable for machining different metals and alloys are predominant now. Ceramic and diamond inserts are the latest cutting tool materials using for the machining of materials having very high hardness.
What are the Basic concepts of Vernier calipers?
A Vernier caliper has many parts. Some of the main parts include an inside jaw, which performs measurements, the depth probe, which finds the depth, and outside jaws, which measure external lengths.
What is weld lap length of reinforced concrete bars?
when length of reinforcing bar is small and we have to provide longer reinforcement in that case the second bar is provided with proper overlapping with the first bar this overlapping is known as lap length.
the straight length of shall not be less than 12mm dia and 200mm length.
How the change a 220 volt generator to 380 volt 3 phase?
The motor has to be a dual voltage motor for this operation to happen. This will be a six coil motor. Each motor coil will be rated for a 220 volt drop across it. For the high voltage connection the motor's coils are connected in series between L1 and L2, L2 and L3, and L3 and L1. For the low voltage connection the motor's coils are connected in parallel between L1 and L2, L2 and L3, and L3 and L1.

What is a watch glass used for?
A watchglass can be used as a beaker cover, but you can also place small amounts of chemicals on it and then heat it (for example, to evaporate some water from a wet chemical).
From Wikipedia:
A watch glass is a circular, slightly concave piece of glass used in chemistry as a surface to evaporate a liquid, or as a cover for a beaker. The latter use is generally applied to prevent dust or other particles entering the beaker; the watch glass does not completely seal the beaker, and so gas exchanges still occur. When used as an evaporation surface, a watch glass allows closer observation of precipitates or crystallisation, and can be placed on a surface of contrasting colour to improve the visibility overall. Watch glasses are so named because they are identical to the glass used for the front of old-fashioned pocket watches. In reference to this, large watch glasses are occasionally known as clock glasses.
See the Related Questions and Web Links to the left for a picture of watch glass and more information about other laboratory apparatus.
Monel Alloy 400 is readily joined by conventional process and procedures, Most of conventional welding process may be used to Join Monel Alloy 400 tto itself or disimilar alloys.
Robotic welding is welding that is done by programmed, mechanical machines. Such robots are commonly used in factories, notably in vehicle manufacturing, and are usually running continuously, day and night. Other robots are used in spray painting often done in situations hazardous to employees, and on assembling lines.
Why is the haber process not run at a high pressure?
because in this process a mixture of nitrogen and hydrogen is heated at 400 to 450c
What is the list to convert number drill bits to metric drill bits?
I, and many technical people have whole pages of lists like this in our diaries or notebooks. My list has all number drills and SAE and Metric comparable sizes.
You may find it easiest by Googling it and copying the list.
How do you test partial penetration welds?
Partial Penetration Weldments could be tested using Ultrasound Testing method. It should not be used to evaluate the intergrity of the weld but could be used to detect the root penetration and the depth.

Why rupture strength is preferred to ultimate rupture strength?
Ultimate strength is used for materials that yield before breaking, like metals; rupture strength is for materials that break suddenly, like glass. Ultimate rupture strength would imply some yield strength before finally breaking and is not a preferred term for brittle materials like glass.
How is a 380v 3-phase machine to a 208v simple phase outlet possible?
if you wound 3-phase on primary of transformer and secondary side we have to only one cable only such a way that it works as a step down transformer.
AnswerYou cannot run a three-phase machine directly from a single-phase (which is what I assume you mean) supply. It won't start. The voltage difference is irrelevant.
Although a lathe can bore and drill, it is actually associated with turning.
A drilling machine is associated with drilling, a milling machine with milling, and a boring mill with boring.
What filler metal is used to weld 308 stainless steel?
