A solid square rod is cantilevered at one end, as shown below. The rod is 0.6 m long and supports a completely reversing transve
rse load at the other end of \pm2 kN. The material is AISI 1080 hot-rolled steel with Sut = 770 Mpa and Sy = 420 MPa. If the rod must support this load for 104 cycles with a design factor of 1.5, what dimension should the square cross section have? Neglect any stress concentration at the support end. Use surface factor ka = 0.488, size factor kb = 0.85, and all other factors equal to one.

Answer:
a) 199.04 ohms
b) attached in image
c) -0.696dB
Explanation:
We are given:
Fc = 8Khz = 8000hz
a)Using the formula:
R = 199.04 ohms
b) diagram is attached
c)
At F = 20KHz and Fc= 8KHz we have:
=0.923
|H(F)| in dB = 20log |H(F)|
=20log0.923
= -0.696dB
Answer:
Explanation:
From the question we are told that:
Incremental resistance
Resistor Feed
Supply Change
Generally the equation for voltage rate of change is mathematically given by
