Answer:
F = 33,324,295.32N
Explanation:
We will first of all find the height at which the plate is inclined. We use sine rule in this case
SinΘ = Opp/hyp
Opp=h, hyp=19m, Θ=35°
h = 19xSin35 = 10.899m
Therefore height h=10.899+4 = 14.899m
We then Calculate Area of the plate
Area = 12x19 = 228m²
Finally, we use an online software to calculate the Hydrostatic pressure
The result from the online computation is attached.
The pressure is p = 146159.19Pa
But pressure p is
Pressure=Force/Area
Making Force the subject
Hydrostatic Force = Pressure x Area
F= 146159.19 x 228 = 33,324,295.32N
F = 33,324,295.32N
Answer:
(a) 2.5 and 6 seconds
(b) 265 HB (27 HRC)
Explanation:
(a) A horizontal line at 550°C intersects the 50% and reaction completion curves at about 2.5 and 6 seconds, respectively; these are the times it will take for the austenite-to-pearlite reaction to go to 50% completion
(b) The pearlite formed will be fine pearlite. From Figure 10.30a, the hardness of an alloy of composition 0.76 wt% C that consists of fine pearlite is about 265 HB (27 HRC).
Answer:
avoid them by choosing not to drive if you expect severe weather.
