    Two ships leave at the same time from one port bound to another port 180m away and one arrived two hours before the other. If the different in the speed of the ships is 3m/s, find their speeds.     31 AugustComment

    what is overhauling an engine?     13 May 2012Comment
    • andy chuks It is major engine work that usually requires removing the engine from the vehicle, and rebuilding or replacing internal components (e.g. pistons, connecting rods, valves). A complete engine overhaul involves replacing piston rings, reboring or honning cylinder walls, replacing pistons (if the cylinders are rebored), replacing main and connecting... Read All

  • precious ahunsi What is formula for Sphere?
    formula for sphere     30 November 2010Comment
    • andy chuks Volume of a Sphere is = 4/3(pie * r^3) Surface Area of a Sphere = 4(pie * r^2)

    formula for work done     14 October 2010Comment
    • JP Williams Work done is force applied to move a body over a distance. Therefore work done is force x distance = F x d. Note workdone can be in various forms it can be f x coso x d where the force is applied at an angle along a plne. Workdone can also be 1/2MV^2 etc

    • andy chuks In thermodynamics, work done on a system is dW = -pdV where W= work done, p=pressure, V=volume W = - S pdV (where S is integral sign) For a closed system

  • precious ahunsi strain
    what is strain     12 October 2010Comment
    • andy chuks Strain is a measure of distortion or deformation of a body relative to the original state of the body. It can be - Linear Strain: We define it as change in length of the body over the original length. Strain = (L2 - L1)/L - Volumetric Strain: Here we define it as change in volume over the original volume. Strain = (V2 - V1)/V - Shear Strain:... Read All

    what is stress     11 October 2010Comment
    • andy chuks Stress is defined as Force per unit area. Stress can be Linear (Tensile or Compressive), Shear, Bulk/Volumetric. Stress = Force/Area = F/A

  • andy chuks Definition and Introduction to Mechanics
    Mechanics the branch of physics concerned with the behavior of physical bodies when subjected to forces or displacements, and the subsequent effects of the bodies on their environment. It is the study of the way matter and forces interact with each other. Here we are concerned with rigid macroscopic bodies, i.e., bodies that you can easily see, do not...
