A home has a 12-VAC door chime system activated by a pushbutton switch at the front door and another at the front yard gate. A buzzer is located in the kitchen. It is operated from the same 12-VAC transformer as the chime system. The buzzer is sounded by pressing a pushbutton switch in the master bedroom or another pushbutton switch in the nursery. Refer to Scenario 319.106. The front door switch is connected in ___ with the door chime and the 12-VAC transformer.

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.

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.
