the calculations that come into play in this procedure. The design will be based on the parameters and function of a normal leg and also on the current available prosthetic legs. In prosthetic leg calculations‚ the main factors to consider are the kinematics‚ kinetics and the energetics. Kinetic quantities are computed by first measuring the external forces acting on the body. For normal walking‚ the external forces are simply the net force of the ground (i.e.‚ ground reaction force‚ or GRF)‚ and the

the object and the velocity of the object must be calculated. To find the velocity‚ kinematics was used. Because the object has no initial vertical velocity and only horizontal velocity‚ the initial velocity can be found by dividing the horizontal displacement by the amount of time the object was in the air. However‚ there are two unknown variables in that equation‚ so time must be calculated using vertical kinematics. Time can be isolated and solved for by taking the square root of two times the vertical

In this part of Lesson 2‚ we will focus on the first type of problem - sometimes referred to as horizontally launched projectile problems. Three common kinematic equations that will be used for both type of problems include the following: Equations for the Horizontal Motion of a Projectile The above equations work well for motion in one-dimension‚ but a projectile is usually moving in two dimensions

Seismic stability of embankments on soft soils has been addressed by many researchers in the past with approximation for pseudo-static condition with and without reinforcement but based on consideration of axial pull in the reinforcement. The kinematics of deformation of typical failure of reinforced embankment dictates oblique pull in the reinforcement due to sliding mass. This oblique pull mobilizes additional normal stresses resulting in higher shear resistance and addition normal force than

Experiment 2: Kinematics of Human Motion Abstract Kinematics is the branch of classical mechanics that describes the motion of bodies and systems without consideration of the forces that cause the motion. There are four activities done in this experiment‚ graphical analysis of human motion‚ where displacement vs. time and velocity vs. time were graphed. Graphical analysis of motion where in the 10th seconds the total displacement is 14.69m‚ average velocity is 1.47 m/s. Reaction time where

The aims of this experiment are to compare the gait pattern in a middle age man in two phases‚ run and walk by comparing kinematic and kinetic data. With the help of digital camera technology and track manager software the result of this experiment us precise and close to reality. 2-INTRODUCTION Through human history‚ people were always curious about the movement involve

To achieve this‚ engineering design requirements must be expressed as assembly tolerance limits. The designer must assign limits to the gaps‚ clearances and overall dimensions of an assembly which are critical to performance. Assembly tolerance limits
