Answer: The wave is traveling in the - x direction.
Explanation: The parameter in a wave function determines the direction of the wave is "ωt"
Where ω = angular frequency(in hertz ) and t = time taken (in seconds)
The product of ωt = 2π which is angular displacement in radian.
A negative value of the of ωt means the wave is traveling in the negative direction.
Also a positive value of sin ωt means the wave is traveling in the positive direction
To replace all forces on a pipe by the equivalent force
T= 8× 50 = 400lb.in
M = 16.30 = 480lb.in
F₂ = 50lb
To calculate the polar moment of inertia of shaft is
J = π/π²×(R⁴-r⁴)
= π²/2×(0.875⁴ - 0.750⁴)
= 0.423in.³
To calculate the moment of inertia
J= 1/2(J)
=1/2 (0.423)
=0.21188in.³
To calculate shear flow
Qy= 2/3(R³-r³)
= 2/3(0.875³- 0.750³)
= 0.16536in.³
To calculate the thickness of the shaft
t= R-r = 0.875 - 0.750 = 0.125 in.
The stress due to torsions is.
Tx = TR/J = 400 × 0.875/0.42376
=825. 9psi.
The stress due to bending
Qx =My/T = 480 × 0.875/0.2118
=1982.3psi
The stress due to transverse shear
Qx = VQ/I(2t)
=50 × 0.16536/0.2118× 0.250
=156.1psi
Answer:
a) Dalton
Explanation:
In <u>Dalton's</u> model atoms are imagined as tiny balls. This model was introduced in the year 1803 by John Dalton.
B. Energy
A power company charges its customers for electricity based upon B. Energy.
<h3>
Explanation:</h3>
Kilo-watt Hours (kWh) is the unit that measures the electricity consumption of customers. Since Power is defined as the rate at which electrical energy is transferred by an electrical circuit per unit time,
If energy is transmitted at a constant rate over a period of time, the total energy in kilowatt hours is the product of power in kilowatts(kW) and time in hours (h)
The tension on point 1 for the three objects moving on a horizontal frictionless surface is 4 N.
<h3>Net acceleration of the masses</h3>
The acceleration of the masses is determined from the net force acting on the mass.
a = ∑F/∑m
a = (3F - 2F)/ (m + 2m + 3m)
a = F/(6m)
<h3>Tension at point 1</h3>
T1 = m₂a
T1 = (2m) x a
T1 = (2m) x F/(6m)
T1 = (2F)/6
T1 = (2 x 12)/6
T1 = 4 N
