hi guys... can you please help me with these problem? it says... a vertical solid steel post 25 cm in diameter and 2.5 m long is required to support a load of 8000 kg. you can ignore the weight of the post... what is the stress in the post? what is the strain in the post? and what is the length...

the log is traveling 50 meters per second.. yeah i think its 200 meters..ok.. i got it.. thanks guys...

hi everybody.. can i ask how to get a coefficient of kinetic friction if a 20 kilogram sled is being pulled across a horizontal surface at a constant velocity. The pulling force has a magnitude of 80 Newton and is directed at an angle of 30 degrees above the horizontal. please answer my...

hi guys.. could you please explain why 2.0x10^1 meters is the answer of the horizontal distance between the log and the bridge when the stone is dropped from rest from a 75-m-high bridge and lands on the log as it passess under the bridge if the log moves with a constant speed of 50 meters per...

A cable lifts a 1200kilogram elevator at a constant velocity for a distance of 35 meters. What is the work done by: a.) the tension in the cable b.)the elevators weight?

could you please answer this? During a tug of war, team A pulls on team B by applying a force of 1100 Newton to the rope between them. How much work does team A do if they pull team B toward them in a distance of 2 meters?

hi guys.. can i ask you about this problem? A log is floating on swiftly moving water. A stone is dropped from rest from a 75meter high bridge and lands on the log as it passes under the bridge. If the log moves with a constant speed of 5 meters per second, what is the horizontal distance...

hi guys.. could you please answer this?A 20 kilogram sled is being pulled across a horizontal surface at a constant velocity. The pulling force has a magnitude of 80 Newton and is directed at an angle of 30degrees above the horizontal. Determine the coeffecient of kinetic friction... please i...

guys.. can you please help me with this simple problem my instructors gave us for home work... its about projectile motion.. what is the time if the displacement is at 21 meters having a 35degrees angle with the original velocity of 100m/s.
