An astronaut in a maneuvering unit approaches a space station. At the present instant, the station informs him that his position relative to the origin of the station's coordinate system is r G evec {r}_G = 40 i bf{i} + 75 j bf{j} + 175 k(m) bf{k}(rm m) and his velocity is v evec {v} = 4.1 j bf{j} + 2.4 k(m/s) bf{k(rm m/s)} . The position of an airlock is r A evec {r}_A = 0 i bf{i} + 25 k(m) bf{k}(rm m) .
Determine the angle between his velocity vector and the line from his position to the airlock's position.
Cooling and Heating Load Estimate using CAMEL program library and the data from DA-9
Determine the stress in a stay at a given temperature. A steel 'stay' of effective length 5m is fitted in between the walls of a ships refrigerated compartment when the temperature is 18 degrees centigrade.
Assuming a coefficient of static friction equal to 0.2 at the common surface, find the maximum torque that may be transmitted by the flywheel without slippage.
determine the force exerted by each cylinder in raising the crate for u = 60°, a 5 0.70 m, and L = 3.20 m. Show that the result obtained is independent of the distance d.
The system on site is a pressure sand filter, with a service curve. The filter is backwashed using the feed pump, at a higher flow rate, shown as backwash curve. What is the speed of the pump to achieve the service and backwash flow rates ?
