If the externally applied force (F) is equal to the force of kinetic friction, F k, then the object slides at constant velocity, and the coefficient of friction involved is called the coefficient of kinetic friction, Î¼ k. In order to find the coefficient of kinetic friction between two surfaces, the horizontal surface method may be used as follows: Horizontal Surface Method: Referring to Fig. 1, it is clear that M has a tendency to move to the right because of F = mg. F is resisted by the ...
The prevalence of the GYS1 mutation in Belgians is as much as 50% of and 8% of the Quarter Horse-related breeds. Horses make and store abnormal muscle glycogen and cannot tolerate dietary starches and sugars. Horses with PSSM can be maintained with low-starch and low-sugar rations and precise exercise protocols. Symptoms usually begin by 2 to 3 years of age. Some horses are subclinical. Clinical signs include skin twitching, stiffness, firm painful muscles, sweating, weakness, and reluctance to move with light exercise.
The muscles of a horse with PSSM are unable to properly store glucose (sugar) so it is unavailable when needed for energy. Two forms have now been identified: Type 1, which is caused by a genetic mutation, and Type 2, the cause of which has yet to be determined.
