Answer:
a. radius = 0.0006m = 0.6mm and length =0.393m = 393mm
b. frequency =377.86Hz
Explanation:
Given:
mass of steel= 4g = 0.004kg
density of steel = 7890kg/m3
tensile stress of steel 7.0x10⁸
tension load =900N
from the density, we will calculate for the Volume of the steel string
density = mass/volume
volume = mass/density = 0.004/7890 = 5.07 x 10⁻⁷ m³
from the tensile stress will can get the maximum base Area of the string ,
tensile stress = load/area =
7x10⁸ = 900/A
A = 900/7x10⁸ = 1.29x10⁻⁶ m²
Area = πr²
area/pi = 4.105x10-7
radius = 0.0006m = 0.6mm
volume = Area x length
length = vol/area =(5.07 x 10⁻⁷ m³)/1.29x10⁻⁶ m² = 0.393m
b. the highest possible frequency is given by:
F =
where T= tension, m=mass, L=length
F =
= 297.04/0.786
frequency =377.86Hz

Answer:
(b) 1440
Explanation:
As the coupon rate of 8% is greater than the yield to maturity (YTM) of 6% annually, the bond is selling at a premium. Hence, the bond will be called at the earliest i.e. 15 years.
Coupon = Call Price * Semi-annual coupon rate = X * [0.08 / 2] = X * 0.04
Yield to call = 6% annually = 3% semi-annually
Time = 15 years * 2 = 30
We know that,
Current Price of bond = Coupon * [1 - (1 + YTC)-call date] / YTC + Call Price / (1 + YTC)call date
- 1,722.25 = [X * 0.04] * [1 - (1 + 0.03)-30] / 0.03 + [X / (1 + 0.03)30]
- 1,722.25 = [X * 0.04] * 19.60 + [X * 0.41]
- 1,722.25 = X * [(0.04 * 19.60) + 0.41]
- X = 1,722.25 / 1.194
-
X=$ 1,442.42 \approx $ 1,440
