Calculate the power required to move a vehicle with tractive resistance of 280 N over a horizontal surface at a constant speed of 18m's?
By Tractive Resistances I assume the total driving resistances including air resistance, rolling resistance etc.. In this to move the vehicle at a constant speed the driving force should be equal to tractive resistance. This means driving force at wheel is 280 N. Power = Force * Velocity 280 * 18 = 5040 W = 5.04 KW.
How do you work out tractive effort?
To calculate tractive effort, you need to know the weight of the vehicle or object being pulled and the coefficient of friction between the tires or wheels and the surface. Tractive effort is calculated by multiplying the weight by the coefficient of friction. This gives you the force required to move the object against resistance.
Which was more powerful the bigboy locomotive or the diesel locomotive?
Modern day diesel electrics have greater tractive effort than the UP 4000 class. The GE ES44ac generates 183,000lbs of tractive effort at start up and have a continuous tractive effort of 166,000lbs. A Big Boy can only get up to 135,000lbs of tractive effort
What is the Meaning of tractive force?
Tractive force is 'static friction'. Like the friction experienced between your car tyres and the road when accelerating from a stand-still.
What is traction motor?
traction means propulsion of vichel and traction motor means the motor which propel the our object and it have tractive effort thats why we are saying traction and it is used in railways
Dc resistance of diode is a static resistance b dynamic resistance c high resistance d zero resistance?
B - Dynamic resistance
How do you calculate contact resistance?
Resistance is resistance , no matter if it is contact resistance or any other resistance. And formula is R = V / I.
What is abrasion resistance?
abrasion resistance is the resistance in abrasion
Comper between the theortical resistance and the partical resistance?
The theoretical resistance simply defines what resistance is while practical resistance refers to putting the theoretical resistance into action.
What is conductors insulators superconductors and semiconductors rank in order of least resistance to most resistance?
Superconductors have no resistance. Conductors have low resistance, semiconductors have intermediate resistance, and insulators have high resistance.
What is PFA material?
Corrosion Resistance
What is Zener resistance of the Zener diode?
zener resistance of a zener diode is the resistance of the zener diode but which is the resistance of a diode
