-. A particular electronic device is known to contain only 10-, 22-, and 48-52 resistors, but these resistors may have 0.25-, 0.5-, or 1-W ratings, depending
on how purchases are made to minimize cost. Historically, it is found that the
probabilities of the 10-S2 resistors being 0.25, 0.5, or 1 W are 0.08, 0.10, and
0.01, respectively. For the 22-S2 resistors the similar probabilities are 0.20,
0.26, and 0.05. It is also historically found that the probabilities are 0.40,
0.51, and 0.09 that any resistors are 0.25, 0.50, and 1 W, respectively. What
are the probabilities that the 48-S2 resistors are (a) 0.25, (b) 0.50, and (c) 1 W?

The force on a cutting tool are 2600n vertically downward and 2100 horizontal. determine the resultant force acting on the tool and the angle at which it acts.

Steel is coated with a thin layer of ceramic to protect against corrosion. what do you expect to happen to the coating when the temperature of the steel is increased significantly? explain.

Aloaded platform of total mass 500 kg is supported by a dashpot and by a set of springs of effective stiffness 72 kn/m. it is observed that when the platform is depressed through a distance x = 12.5 cm below its equilibrium position and then released without any initial velocity; it reaches its equilibrium position in the shortest possible time without overshoot. find the position and velocity of the loaded platform 0.10 sec. after its release. if a further load of 400 kg is added to the platform, find, i) the frequency of damped vibrations, and i) the amplitude of vibration after 2 complete oscillations, given that the initial amplitude is 15 cm.
