Situation 3. The force system shown consists of the couple C and four forces. If the resultant of this system is 75000 N-mm counterclockwise couple, determine P, Q and C. y 100 N 12 А C 5| 30 mm P 400 N 3 В d l- 30 mm

Consider the force shown in the figure below. If the y-component of the force is Fy = 16.0 N and the angle is θ = 22.0 ◦ , then the x-component and magnitude of the force are A. Fx = 0 and |F~ | = 16.0 N B. Fx = −16.0 N and |F~ | = 22.6 N C. Fx = −39.6 N and |F~ | = 42.7 N D. Fx = −6.46 N and |F~ | = 17.3 N

#1. Three lab partners (Bob, Alice and Max) are discussing an incline problem (see diagram). They are debating the value of the normal force. Bob claims that the normal force is 250 (N); Alice claims that the normal force is 433 (N) and Max claims that the normal force is 500 (N). While all three answers seem reasonable, only one is correct. Indicate which two answers are wrong and explain why they are wrong. Fnorm Friet 30° .. grav 500 N

22. An elevator weighing 2000lb (force) attains an upward velocity of 16fps in 4sec with uniform acceleration. What is the tension in the supporting cable? Use g=32.2ft/s^2 * O 1752lb 8062lb O 2815lb 2250lb

It is not possible to see very small objects, such as viruses, using an ordinary light microscope. An electron microscope can view such objects using an electron beam instead of a light beam. Electron microscopy has proved invaluable for investigations of viruses, cell membranes and subcellular structures, bacterial surfaces, visual receptors, chloroplasts, and the contractile properties of muscles. The "lenses" of an electron microscope consist of electric and magnetic fields that control the electron beam. As an example of the manipulation of an electron beam, consider an electron traveling away from the origin along the x axis in the xy plane with initial velocity v, = vî. As it passes through the regic x = 0 to x = d, the electron experiences acceleration a = aî + aj, where a, and a are constants. For the case v, = 1.91 x 10 m/s, a = 8.21 x 1014 m/s?, and a, = 1.73 x 1015 m/s?, determine the following at x = d = 0.0100 m. (a) the position of the electron Y = m (b) the velocity of…
