Air is used as the working fluid in a simple ideal Brayton cycle that has a pressure ratio of 12, a compressor inlet temperature of 300 K, and a turbine inlet temperature of 1000 K. The properties of air at room temperature are cp=1.005 kJ/kg⋅K and k=1.4 .         Determine the required mass flow rate of air for a net power output of 66 MW, assuming both the compressor and the turbine have an isentropic efficiency of 85 percent. The required mass flow rate of air is _________ kg/s.

Discuss how flip-flops may be used for dividing the frequency of a periodic wave.

Q1. 6/4 GHz TDMA mobile communication system with gain of transmitted antenna Station of 1000, sum of additional losses is 5 dB, Transponder input backoff Is 2 dB, Uplink energy per bit to noise ratio is 3, Transmission bit rate 8kb/sec Margin for intersymbol distortion is 2, the bandwidth of channel is 9.6MHz, Uplink (G/T.) is 8.Calculate Uplink power for this system

In the previous solution he said i1^2=i2^2 why because u don’t know the angle can anyone solve it using the phasor method

F T = 450 Nm A ☑ 100 mm B 500 mm 1000 mm Şekil, 52 kN eksantrik yük taşıyan bir sonsuz mili göstermektedir. Mil radyal ve eksenel yük taşıyan rulmanlarla yataklanmıştır. Yük şekilde gösterildiği gibi somuna asılmış ve dönmeyi engellemektedir. Sürtünmeyi yenip yükü kaldırmak için uygulanan tork 450 Nm'dir. A ve B noktalarındaki gerilmeleri hesaplayınız. Milin, AISI 4140 540°C'DE temperlenmiş alaşımlı çelik olduğu bilindiğine göre maksimum kayma gerilmesi teorisine göre emniyetli olup olmadığını belirleyiniz. The figure shows a worm shaft carrying a 52 kN eccentric load. The shaft is supported by bearings that carry radial and axial loads. The load is suspended from the nut, as shown, preventing rotation. The torque applied to overcome friction and lift the load is 450 Nm. Calculate the stresses at points A and B. Knowing that the shaft is made of AISI 4140 alloy steel tempered at 540˚C, determine whether it is safe according to the maximum shear stress theory. 400 mm

How can I solve it

The structures in the following problems are single-story, one-bay assemblies representing one common lateral force- resisting systems used in buildings: Moment-Resisting Frames (MRFS). Each frame is fix-connected at its base. Your tasks are as follows: 1. 2. Solve for the support reactions (vertical, lateral, and moment) under the applied lateral load. Determine member end forces (axial, shear, and moment) for all relevant structural members.

Determine member end forces (axial, shear, and moment) for all relevant structural members. 1. 2. 3. Draw internal force diagrams (bending moment) for the required elements. 4. Determine the lateral deflection of joint B Be sure to clearly label your diagrams and show all work leading to your solutions. You must use the slope deflection equations to solve the problem, otherwise it will take forever. Use dimensions referenced to elements' centerlines. You shall neglect axial and shear induced deformations.
