Answer:
machine guarding
Explanation:
Machine guarding protects an operator from the point of operation.
Answer:
The steady-state temperature difference is 2.42 K
Explanation:
Rate of heat transfer = kA∆T/t
Rate of heat transfer = 6 W
k is the heat transfer coefficient = 152 W/m.K
A is the area of the square silicon = width^2 = (7/1000)^2 = 4.9×10^-5 m^2
t is the thickness of the silicon = 3 mm = 3/1000 = 0.003 m
6 = 152×4.9×10^-5×∆T/0.003
∆T = 6×0.003/152×4.9×10^-5 = 2.42 K
Answer:
29 percent
Explanation:
The transportation sector is the highest contributing factor to greenhouse gas emissions in the world. Vehicles such as cars, motorcycles, airplanes, ships etc all emit these gases which causes global warming.
Electric cars is known not to little or zero direct emission and known to be safer. It however emits nitrogen oxide which is fog like in a very minute quantity.
Whipping is done in a forward direction. You deposit a dab or puddle of metal down, and then whip the rod forward and up a little to let that dab cool a bit, then you move back and deposit another dab slightly ahead of the previous dab.
Cellulose rod like 6010 and 6011 are known as "fast freeze" electrodes, also known to be deep penetrating rods. The "whip and stitch" motion is used so that you get the full benefit of the cellulose characteristics. The forward motion basically gouges out the base metal, and it gets filled in with the back-step.
Hope this helped:)
