Need this badly today
What work is done on a level track in bringing the velocity of a train weighing 200metric tons from zero to 45 kph, if the frictional resistance at any velocity is 45N/ton, and if the change in speed is accomplished in length of 1000m? (Ans. 26780.95 KN/m)
C. If the track were a 1% upgrade, what would be the additional work to be done?

Tension and stress of a chain lifting a beam
The 5m uniform steel beam has a mass of 600 kg and is to be lifted from the ring at B with the two chains, AB of length 3m., and CB of length 4m. a.)Determine the tension T in chain AB when the beam is clear of the platform. b.) stress if the cross-sectional area is limited to 500 mm2.

Value of a Bond
Value of a Bond
It is defined to be the present worth of all the amounts the bondholder will receive through his possession of the bond.
The bondholder will receive two types of payments which are:
1. Single payment which the owner will receive at the date of maturity of the bond, which is usually equal to the par value of the bond; and
2. The periodic payments for interest on the bond usually it is redeemed by the issuing corporations.
Formula for value of a bond:

Dynamics
Hi! Pahelp please? Anyone who has a good heart huhuhu. I badly need your help. Anyone who can answer this? I mean with the process.
The collar has a mass of 3kg and is supported on the rod having a coefficient of kinetic friction Uk=0.4. The attached spring has an unstretched length of 0.2m and stiffness k=50N/m. Determine the speed of the collar after the applied force F=200N causes it to be displaced s=1.5m from pt. A. When s=0 the collar is held at rest?
What is the process?
