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
Answer:
a) s = 42 m
b) V = 26 m/s
c) a = 11 m/s²
Explanation:
The velocity(V) = 2 - 4t + 5t^3/2 where t is in seconds and V is in m/s
a) To get the position, we have to integrate the velocity with respect to time.
We get the position(s) from the equation:
Integrating both sides,
Integrating, we get
But at t=0, s(0) = 2 m
Therefore,
c = 2
Therefore
When t = 4,
s = 42 m
At t= 4s, the position s = 42m
b) The velocity equation is given by:
At t = 4,
V = 2 - 16 + 40 = 26 m/s
The velocity(V)at t = 4 s is 26 m/s
c) The acceleration(a) is given by:
Differentiating with respect to t,
At t = 4 s,
a = 11 m/s²
Answer:
The GMAW process commonly uses a constant voltage power source (GMAW-CV) that allows for a relatively constant welding voltage output over a range of welding currents. For GMAW-CV the welder selects the wire feed speed (WFS) on the wire feeder unit and an appropriate voltage on the welding power supply.
