linear motion into rotating motion. Connecting rods may also convert rotating motion into linear motion. Historically‚ before the development of engines‚ they were first used in this way. INTRODUCTION In this laboratory we will investigate the kinematics of some simple mechanisms used to convert rotary motion into oscillating linear motion and vice-versa. The first of these is the slider-crank - a mechanism widely used in engines to convert the linear thrust of the pistons into useful rotary motion

How to write a lab report Let’s take as an example a free-fall experiment. You drop a small steel ball from various heights and use an electronic timer to measure how long it takes the ball to hit the ground. From this you calculate the final speed of the ball using v = 2x/t. You believe that the ball will have a constant acceleration of “g‚” 9.8 m/s2. This will be seen if you graph velocity vs. time and get a straight line with a slope of 9.8. You end up with a table of data giving distances

Fluid mechanics is the branch of physics that studies fluids (liquids‚ gases‚ and plasmas) and the forces on them. Fluid mechanics can be divided into 1) fluid statics‚ the study of fluids at rest; 2) fluid kinematics‚ the study of fluids in motion; 3) fluid dynamics‚ the study of the effect of forces on fluid motion. Fluid Mechanics Overview Fluid is a substance that is capable of flowing. It has no definite shape of its own. It assumes the shape of its container. Liquids and gases are

Post-Stroke Rehabilitation Stroke‚ if survived‚ is the largest cause of long-term disabilities in the United States. Nearly 160‚000 Americans have strokes every year‚ killing one of three individuals (reference?). Due to our nation’s ageing population‚ the stroke epidemic is expected to increase nearly 25% by year 2030 (Brewer‚ 2012). These stroke-related disabilities impact the survivor’s quality of life and independence in everyday activities. Nearly 50% to 75% of all stroke survivors have residual

Stroke is the sudden death of brain cells due to lack of oxygen which is caused by blockage of blood flow or rupture of an artery in the brain. The most common symptoms are weakness or numbness of muscles of face‚ upper extremities and lower extremities on one side of the body. Loss of speech‚ difficulty in speaking‚ loss of balance‚ unable to stand or walk are usually combined with the symptoms. Hemiplegia of the upper extremity is the major cause responsible for the restriction of activities of

Because we did not collect motion capture data‚ we were not able to look at kinematics. However‚ GRFs and COM power are useful for assessing gait symmetry
