Answer:
a) 159.07 MPa
b) 10.45 MPa
c) 79.535 MPa
Explanation:
Given data :
length of cantilever beam = 1.5m
outer width and height = 100 mm
wall thickness = 8mm
uniform load carried by beam along entire length= 6.5 kN/m
concentrated force at free end = 4kN
first we determine these values :
Mmax = ( 6.5 *(1.5) * (1.5/2) + 4 * 1.5 ) = 13312.5 N.m
Vmax = ( 6.5 * (1.5) + 4 ) = 13750 N
A) determine max bending stress
б = 
= 
= 159.07 MPa
B) Determine max transverse shear stress
attached below
ζ = 10.45 MPa
C) Determine max shear stress in the beam
This occurs at the top of the beam or at the centroidal axis
hence max stress in the beam = 159.07 / 2 = 79.535 MPa
attached below is the remaining solution
Answer: (A) Security regression testing
Explanation:
The security regression testing is used to prevent the re-occurring process. The regression testing is the type of the testing that intends to affirm that a program or code or application changes has not influenced existing highlights and it keeps up the agenda.
The agenda ought to be similarly identified with necessity that was concluded. By checking this both then relapse testing occurs and this won't reoccurred from next time.
The regression testing improvements groups must ensure that changes, updates and new discharges don't presents imperfections and vulnerabilities that could be misused by the people.
Answer:
One gallon of paint can cover about 400 square feet of wall.
18 x 15 feet is 270 feet of space.
270/400 = .675 gallons for one coat on one wall
.675 x 4 = 2.7 gallons for one coat on all walls
2.7 gallons x 2 = 5.4 gallons of paint in all
Answer:
we need to see what you're being asked about
Explanation:
According to the basic speed law, if conditions make it unsafe to follow posted speed limits, you should: Reduce your speed to less than the maximum posted speed limit.
<h3>What is the most speed limit?</h3>
The highest published speed limit in the country is 85 mph (137 km/h) and can be located only on Texas State Highway 130, a toll road that bypasses the Austin metropolitan area for long-distance traffic.
<h3>What is the 'rule'? </h3>
The 'rule' itself is quite straightforward: if the speed limit is (for example) 30mph, the rule notes that you won't get a speeding ticket unless you are going 10% plus 2 mph faster than the limit.
