a cantilever beam 1.5m long has a square box cross section with the outer width and height being 100mm and a wall thickness of 8
djverab [1.8K]

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 = \frac{MC}{I}  =  \frac{13312.5 ( 0.112)}{1/12(0.1^4-0.084^4)}  =  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.

How much paint would you need to cover one bedroom wall using 2 coats of paint?
Thepotemich [5.8K]

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

According to the basic speed law, if conditions make it unsafe to follow posted speed limits, you should:____.
lapo4ka [179]

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.
