The cost of delivering a package is based on the weight of the package. There is a flat fee of $5.00 for all packages. In addition to the flat fee, for packages between 2 pounds and 10 pounds there is a weight fee of $1.00 for every pound over 2 pounds. For packages over 10 pounds the weight fee is $5.00 for every pound over 10 pounds. If the package weights over 20 pounds but less than 100 pounds, the weight fee is $10.00 for every pound over 20 pounds. Packages over 100 pounds are not accepted. Write a program to accept the package weight from a user and then display the total cost to deliver the package.

What precautions should you take to prevent injuries when dealing with heavy loads?

The mass flow rate of the fluid remains constant in all steady flow process. a)- true b)- false

Aloaded platform of total mass 500 kg is supported by a dashpot and by a set of springs of effective stiffness 72 kn/m. it is observed that when the platform is depressed through a distance x = 12.5 cm below its equilibrium position and then released without any initial velocity; it reaches its equilibrium position in the shortest possible time without overshoot. find the position and velocity of the loaded platform 0.10 sec. after its release. if a further load of 400 kg is added to the platform, find, i) the frequency of damped vibrations, and i) the amplitude of vibration after 2 complete oscillations, given that the initial amplitude is 15 cm.
