EMA 201 Week 1 1. To steady a sign as it is being lowered; two cables are attached to the sign at A. Using trigonometry and knowing the magnitude of P is 300 N, determine (a) the required angle α if the resultant R of the two forces applied at A is to be vertical, (b) the corresponding magnitude of R . 2. (a) Determine the x and y components of each of the forces shown. (b) Add the three force vectors using Cartesian components. (c) Switch your answer from part b to polar components. (d) Rotate x-y coordinate system 45 degrees counter clockwise and find new x and y components of the resultant vector. 3. Member CB of the vise shown exerts on block

Unformatted text preview: B a force P directed along line CB . Knowing that P must have a 300-lb horizontal component, determine (a) the magnitude of the force P , (b) its vertical component. A mechanical engineer, an electrical engineer and a software engineer are travelling in an old Fiat 500 (Bambino) when all of the sudden the car backfires and comes to a halt. The mechanical engineer says "Ah! It's probably a problem with the valves, or the piston!". The electrical engineer says "Nonsense! It's most probably a problem with the spark plugs or the battery!". The software engineer says "How about we all get out of the car, and get back in again"....
