Explanation:
Given that:
x(t) = 10 sin(10t) . sin (15t)
the objective is to find the power and the rms value of the following signal square.
Recall that:
sin (A + B) + sin(A - B) = 2 sin A.cos B
x(t) = 10 sin(15t) . cos (10t)
x(t) = 5(2 sin (15t). cos (10t))
x(t) = 5 × ( sin (15t + 10t) + sin (15t-10t)
x(t) = 5sin(25 t) + 5 sin (5t)
From the knowledge of sinusoidial signal Asin (ωt), Power can be expressed as:
For the number of sinosoidial signals;
Power can be expressed as:
As such,
For x(t), Power
For the number of sinosoidial signals;
For x(t), the RMS value is as follows:
Answer:
The minimum diameter is 1.344 in
Explanation:
The angular speed of the driveshaft is equal to:
Where
N = rotational speed of the driveshaft = 2900 rpm
The torque in the driveshaft is equal to:
Where
P = power transmitted by the driveshaft = 134 hp = 73700 lb*ft/s
The minimum diameter is equal to:
Where
T = shear stress = 6100 psi
τ = 242.68 lb*ft = 2912.16 lb*in
