63 + 216 Ω ∅ ⁄ empedansına sahip dengeli ∆ bağlı bir yük 50∠0° Ω ∅ ⁄ empedansına sahip dengeli bağlı bir yüke parallel bağlıdır. Paralel yükler 1 + 3 Ω ∅ ⁄ empedansına sahip bir hattan beslenmektedir. Bağlı yükün hattan nötr'e geliminin büyüklüğü 750 'tur. a) Yükleri besleyen hattaki akımın büyüklüğünü hesaplayınız? b) Hattın gönderici ucundaki faz geriliminin büyüklüğünü hesaplayınız? c) Kaynaklar tarafından sağlanan toplam görünür, ortalama ve reaktif güçleri bulunuz?

An electrical motor raises a 50kg load at a construct velencity .calculate the power of the motor, if it takes 40sec to raise the load through a height of 24m(take g =9.8n/g)

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.

Afull journal bearing has a journal diameter of 27 mm, with a unilateral tolerance of -0.028 mm. the bushing bore has a diameter of 27.028 mm and a unilateral tolerance of 0.04 mm. the l/d ratio is 0.5. the load is 1.3 kn and the journal runs at 1200 rev/min. if the average viscosity is 50 mpa-s, find the minimum film thickness, the power loss, and the side flow for the minimum clearance assembly.
