Work force and distance are related to each other. Thus the net force which can be found through the equation fma is 0. From the question details provided im assuming that the block is being lifted up vertically at a constant velocity. Where m mass. 148 to 193 lbs. 119 to 142 lbs.
Knowing your body mass index can help you to steer clear of such unhealthy. G acceleration due to gravity. How to calculate your optimal weight and height method 1. Also note that when you lift a 1 lb weight upward by a distance of 5 ft the work performed is also 5 ft lbs. So that should amount to not less than m g h 501018 900 joules. Enter the required values know the unknown value of work or force or distance.
Lighter work such as precision work or inspection tasks that are visually intense should be higher so that you can see better. 10 98 5 490 joules. If your height is lets say 180m then the total mechanical work would be the work done while lifting the suitcase plus some extra work due to the inefficiencies of the human body machinery internals. 4 11 94 to 123 lbs. Quetelet body mass index. 673 views view 3 upvoters.
Note that arm supports are often helpful in these situations. Heavier work should generally be lower than elbow height so that it is possible to take advantage body weight and larger muscle groups of the torso. Stack exchange network consists of 177 qa communities including stack overflow the largest most trusted online community for developers to learn share their knowledge and build their careers. 1 the work you perform on the weight during the lift is thus the work you performed in lifting the 5 lb weight is 5 ft lbs. Answered nov 24 2019 author has 14k answers and 162k answer views. Work force and acceleration are the basic concepts of travel and distance calculations in physics.
Imagine the following case. When you apply a greater force the work done and the distance travelled is high and vice versa. 124 to 147 lbs. 4 10 91 to 118 lbs. The quetelet index is useful in determining the amount of fat in your organism. 5 97 to 127 lbs.
Determine the work done by lamar in lifting. Work done is given by equation. As the velocity is constant the acceleration is 0. 143 to 186 lbs.
