Ok. There are 2 universal beams. One is 500mm deep and the other one is 400mm deep. For both beams, the top and bottom flanges are 200mm wide x 10mm deep. [SPAN of the beams is not given]
Questions is..If the maximum bending moment capacity of the 400mm deep universal beam is 200 kn.m. What...
Homework Statement
Explain if wind on walls and roofs of buildings is considered a pressure or a force?
Homework Equations
P = F/A
The Attempt at a Solution
Wind load should be measured in terms of pressure?..but I don't know the exact reason why it is. Does it have something...
Could you tell me which formula have you used for calculating the bending moment?
say is it: (b*d* ? * ? * span^2 ) /8 = bending moment
what does 2400 and 10 stand for?
Thanks again for the clarifacation.
I would like to know ,
given with the 2 attachments below,
are there any ways to find the bending moment (as circled) of the bridge?
or it is not possible to calculate simply because the "load" data is not given?
Several attempts have been tried but the circled data can not be...
Homework Statement
Calculate the rest mass of Deuterium nucleus.
Homework Equations
Is it correct to calculate its mass using hydrogen?
i.e. 2*rest mass of hydrogen?..
The Attempt at a Solution
As stated in textbook,
the rest mass of deuterium = 3.34330*10^-27 kg
If it is...
Homework Statement
A generator is made from a 100 turn coil, 5.0 cm by 4.0 cm, placed in a magnetic field of strength 0.20 T. The coil rotates at 50 revolutions per second.

Looks like A to me...
Thinking process:
he separation between the induced e.m.f. is 3 seconds. So it is A.
Why 3 seconds?
Consider Alice on the left edge and Bob on the right edge of the B-field grid with the synchronized clocks.
Your own physical prinicple:
The induced emf exists...
