| Summary: | (150 lb), the forces exerted on the force plates (p=0.0001) (p=0.0014)moments at the knee increased. For the longer (p=0.0027), and the dynamic (p=0.0143) and static a curb is a dynamic activity. Recommendations include use of a wheel larger than 20.3 cm (8 in) and redesign of the runner accelerations at the hip (p=0.0442) and L5/S1 (p=0.0145) as accelerations at the shoulder (p=0.0356) and elbow (p=0.0090) also increased for the heavier load. For the smaller and knee (p=0.0260) increased for the heavier load. The and the dynamic moments (P=0.0001) at the shoulder, hip, and the minimum was 158.8 kg (350.1 lb). The average weight at L5/S1 increased. The psychophysical study (n=20) at the elbow (p=0.0001), hip (p=0.0001), L5/Sl (p=0.0001), back. This study concludes that moving a two-wheel cart over biomechanical study (n=4) involved altering the amount of comfortable having on the cart to tilt the cart back and to diameter wheel, the forces exerted on the force plates distance between the load center of gravity and the axle, the items closer to the cart axle. L5/S1, and knee increased. In addition, the static moments maximum weight to tilt back the cart was 225.8 kg (500 lb), move the cart over the curb without excessive strain. The of the average load of 203.0 kg (447.5 lb) to tilt the cart of the load the worker was willing to transport with the cart on the cart. Also, stack loads up until it is necessary to over the curb was 101.8 kg (224.4 lb), which is roughly half psychophysical evaluations of industrial males. The required participants to determine the maximum load each was stack them out on the tongue extension and place heavier standard two-wheel cart to transport loads over a curb. This the load center of gravity. For the heavier load of 68 kg The purpose of this study was to evaluate the use of a was done through biomechanical (static and dynamic) and weight placed on the cart, the diameter of the wheels, and well as the dynamic (p=0.001 1) and static (p=0.0008) moments |
