Answer:
r = 1.922 mm
Explanation:
We are given;
Yield stress; σ = 250 MPa = 250 N/mm²
Force; F = 29 KN = 29000 N
Now, formula for yield stress is;
σ = F/A
A = F/σ
Where A is area = πr²
Thus;
r² = 2900/250π
r² = 3.6924
r = √3.6924
r = 1.922 mm
Answer:
Cost = $2527.2 per month.
Explanation:
Given that
Discharge ,Q = 130 L/min
So

Cost = $0.45 per cubic meter
1 month = 30 days
1 days = 24 hr = 24 x 60 min
1 month = 30 x 24 x 60 min
1 month = 43,200 min
Lets x
x = 0.13 x 43,200

So the total cost = 5616 x 045 $
Cost = $2527.2 per month.
Answer: they would be 300 miles from the station.
Explanation:
At the point where both trains meet, they would have covered the same distance.
Let t represent the time spent by the first train in covering this distance.
Distance = speed × time
The first train leaves the station and travels north at 60km/hr.
Distance covered by the first train is
60 × t = 60t
Two hours later, a second train leaves on a parallel track and travels north at 100km/hr. Time spent by the second train in covering this distance is (t - 2) hours
Distance covered by the second train is
100(t - 2) = 100t - 200
Since both trains covered the same distance, then
100t - 200 = 60t
100t - 60t = 200
40t = 200
t = 200/40
t = 5 hours
The distance that they would be from the station is
60 × 5 = 300 miles
