Solution 1: Ergonomic Assessment and Improvement. An ergonomic assessment of Paula's workstation could identify areas where adjustments could be made to reduce strain on her wrists. This could include adjusting the height of the workstation, providing wrist supports, or changing the design of the tools she uses. The strength of this solution is that it directly addresses the physical strain causing Paula's discomfort. However, the weakness is that it may require investment in new equipment or tools, and the effectiveness will depend on the specific changes made. Solution 2: Job Rotation. Paula could be rotated between different tasks more frequently, reducing the amount of time she spends on tasks that strain her wrists. This could also include training other workers to perform the welding and gaging operations, allowing for more flexibility in task assignments. The strength of this solution is that it reduces the repetitive strain on Paula's wrists. The weakness is that it requires…
a. There are plenty of things in the air you may want to remove-smoke, odors, pollen, allergens, etc. I’ll collectively refer to these as “dust” going forward. Typically, we aim to keep these levels low-in the μg/m3 range. Outdoor air may have 100–300 μg/m3, whereas we strive for much lower values indoors. To do that, we use air filters. A standard air filter is 4 in. (100 mm) thick, 20 x 25 in. cross section, D = 8 × 10-11 m2/s, with no dust in it when it’s new (Co = 0 kg/m3). Suppose the outdoor air has 100 μg/m3 of dust, whereas the indoor we want the indoor air to be less than 20 μg/m3. How long will it take (in years) for the far side of the filter to reach this value? (We will refer to this as the baseline case going forward).
(4) You are interviewing for a job as a see-saw designer. In order to get the job, you must solve a design problem involving a meter-stick with two masses hanging on it (see below). The system is to be perfectly balanced, with the pivot point offset from the center of the meter-stick. The mass of the meter-stick is 65.22 g. To get the job, you must find the unknown mass, m, in grams. 1.00 m F- Fplankt FuiOck, t Foluck0 27.0 cm 13.0 cm 65.22g 500. g 0.63096 나.9 massmissing T= 0,63896(1.0) +.500(-27) +.60 (F) = 0 13.16 grams f =1.289N = 0.1316 9.8 (5) The diagrams show a Fn stationary cargo plane Fn1 Fn2 before and after loading it.

Paula has worked for Brindle Corporation for 3 years. During this time, she has worked as a machine operator/cell leader in various work cells. Recently, the plant went to mandatory 12-hour shifts and plans to remain on this schedule for several months. Paula’s present work cell is manufacturing 3-inch diameter exhaust tubes that are made from stainless steel. These tubes get a hole punched in them, a flange welded on, and burrs ground off. The pipe then gets placed into a gage to check that it was made correctly. (The tubes weigh about six pounds.) Paula has been performing the welding operation. She leans into the machine and loads the part into a fixture then positions the flange. Both pieces are clamped (using hand clamps) into position and the machine is cycled by depressing two palm buttons. The gaging operation requires placing the finished part into the gage and clamping it (using hand clamps) into place. A pin is depressed to verify the position of the hole and a…
