The approximate ductility (%EL) of a brass that has a yield strength of 275 MPa (40,000 psi) is 30%. Ductility can be defined as the ability of a material to be stretched without breaking under tensile stress. The elongation percent (%EL) or strain percent, on the other hand, is a measure of ductility.
Here's the step-by-step process to find the approximate ductility (%EL) of a brass that has a yield strength of 275 MPa (40,000 psi). Yield strength = 275 MPa (40,000 psi). The formula used to find the approximate ductility (%EL) of a brass is:
%EL = (σ fracture - σ yield) / σ yield × 100 whereσ fracture = stress at fracture pointσ yield = stress at yield point.
Calculation Now, let's put the given values in the formula:%EL = (σ fracture - σ yield) / σ yield × 100σ yield = 275 MPaσ fracture is unknown. Therefore, to find the approximate ductility (%EL), we need to know the value of σ fracture.Assuming that the ratio of tensile strength to yield strength for brass is 1.3, we can calculate the value of σ fracture as follows:
Tensile strength = 1.3 × Yield strengthTensile strength = 1.3 × 275 MPaTensile strength = 357.5 MPa.
Substitute the values in the formula:
%EL = (σ fracture - σ yield) / σ yield × 100%EL = (357.5 MPa - 275 MPa) / 275 MPa × 100%EL = 82.5 / 275 × 100%EL ≈ 30%
Therefore, the approximate ductility (%EL) of a brass that has a yield strength of 275 MPa (40,000 psi) is 30%.

suppose that in a certain region that the 3 v and 1 v line of equipotential are seperated by 20 cm. what be strength of the electric fields between these two lines at this separation?
The strength of the electric field between these two equipotential lines at this separation is 10 V/m.
To calculate the strength of the electric field between the 3V and 1V lines of equipotential separated by 20 cm in a certain region, we can use the formula :
E = V/d
where E is the electric field strength, V is the potential difference between the two lines, and d is the separation distance between the lines.
In this case, the potential difference is 2V (3V - 1V) and the separation distance is 20 cm (0.2 m).
Therefore, the electric field strength would be E = 2V/0.2m = 10V/m.
This means that for every meter between the 3V and 1V lines, there is an electric field strength of 10V.

At what distance below the lining surface can disc pad rivets contact a rotor?
OA.2 mm
OB. 1/16th inch
OC. The thickness of the disc pad backing plate
OD. 1/64th inch
Disc pad rivets come into contact with a rotor. This contact generates heat that causes the backing plate to expand. This expansion results in the backing plate pushing the disc pad away from the rotor.
That's why you'll hear a clunk or click when you release the brake pedal. What is the distance at which the disc pad rivets can contact a rotor The answer is option OD, which is 1/64th inch.In a brake system, disc pad rivets should not contact the rotor. If they do, they will wear the rotor prematurely and make a scraping sound. If the brake pads are worn too thin, they will grind against the rotors, causing damage to the rotors and making noise.
thickness of the brake pads and the amount of rotor material remaining are the two most critical measurements in determining if the rotors need to be resurfaced or replaced. If the rotors are worn, they may require replacement, which will be expensive. If the rotors have deep grooves, scoring, or are cracked, they must be replaced.

John has just graduated from State University. He owes $35,000 in college loans, but he does not have a job yet. The college loan company has agreed to give John a break on a deferred-payment plan that works as follows. John will not have to repay his loan for 5 years. During this “grace period” the loan obligation will compound at 4% per year. For the next 5 years, a monthly payment will be required, and the interest rate will be 0.5% per month. What will be John’s monthly payment over the 60-month repayment period?
Answer:
The correct response is "821.88". A further explanation is given below.
Explanation:
According to the question,
The largest amount unresolved after five years would have been:
= \(35000\times (\frac{F}{P}, 4 \ percent,5 )\)
= \(35000\times 1.216 7\)
= \(42584.50\)
Now,
time (t) will be:
= \(5\times 12\)
= \(60 \ monthly \ payments\)
So, monthly payment will be:
= \(42582.85\times (\frac{A}{P}, 0.5 \ percent,60 )\)
= \(42584.50\times 0.0193\)
= \(821.88\)
