Hey i have tried these
questions a few times, can you please show me how you do them with
steps? A diagram with the forces on the bridge sections would be
nice. Thanks you very much!!!!!!!
Since they are roller so there will not be any horizontal reaction
So only vertical components will be there
Considering reaction at A is Na vertically upward and reaction at B is Nb vertically upward.
So taking moment about B
F×3l = Na×4l
So Na= 3F/4
So the correct answer is j
Similarly moment about A
So F×l = Nb×4l
So Nb= F/4.
So the correct answer is h
Hey i have tried these questions a few times, can you please show me how you...
could you please help with
questions 3 and 16
note: question 3) I tried FCFFT FCFFC FCFFF and are all
incorrect
3. [1pt] Answer True, False, or Cannot tell to each of the five statements below. E.g., if the answer to the first statement is 'true' and to the rest, `cannot tell', enter TCCCC. a. A 2 kg and a 3 kg ball are dropped from a tower. The net forces on each are the same. b. A box with...
Please can you tell me if my diagram is correct and how i did it
is correct
Is this correct that I can use 31 for my angle because
it an opposite angle to the angle given in the picture
(a) Find the tension in each cable supporting the 540-N cat burglar. (Assume the angle θ of the inclined cable is 31.00.) inclined cable horizontal cable vertical cable T, sin 31° -540 T,(0.5150) T2(0.5150) T, cos 31°-T, = 0 T,...
Please explain how you approach this so I can emulate your
problem solving strategies on like problems
Suppose we had a large, positively charged plate in an upright (vertical) position and a point charge with positive charge +Q. In lecture, you saw that a large charged plate gives rise to an electric field which is constant in space: we will call this electric field Eplate. Let us suppose also that we had a s bl with positive charge +q and...
I need help to write a nice introduction for experiment 6
please ( no hands write ) typing
Thank you
HEAT TREATMENT OF STEELS EXPERIMENT 6 EXPERIMENT 6 HEAT TREATMENT OF STEELS THEORY The Effect of Cooling Rate One of the most convenient methods for controlling the properties of a given steel, i.e., a steel whose composition is already fixed, consists of austenizing the steel and ten cooling to room temperature at some predetermined rate. A variation of cooling rates...
