27). 2 In the northeastern United States, in which direction does the needle of a magnetic compass point? OEast of geographic north O South of geographic north O North of geographic north West of geographic north 28) Inter-row spacing for a tilted rack array is determined by which factors? O Slope and voltage of modules O Sun angle and tilt of modules O Sun angle and voltage of modules O Rack manufacturer specifications 24) Which type of PV array mounting system is MOST common for a residential application with a sloped, south-facing roof? O Rack mount O Pole mount O Ballasted mount O Standoff mount 30) A specification requires the PV array for a stand-alone PV system to be sized to produce 1.25 times the average daily system load of 80 Ah when the irradiation recelved on the array is 4 peak sun hours. If the selected PV module has STC-rated maximum power current (Imp) of 5 A, how many parallel- connected strings of modules are required? 5 31 Which silicon solar cell manufacturing…

QUESTION 2: What is the approximate voltage amplitude and frequency of the waveform below

A selected structural douglas fir-Larch 4*16 beam on a 20ft span support a hoist located at the center of the span. determine the maximum allowable load on the hoist (including its weight) based on the bending. Assume normal load duration.The beam is supported on a 2*4 top plate. Lateral support is provided onl at the ends of the member and the ends are cosidered pinned.  In addition, this time the beam used is known to be located in the unventilated rafter space of a commercial barn in Louisiana.  As such, the beam will routinely experience both elevated temperatures and humidity.  Assume that the temperature up in the rafters is often between 1100F and 1200F.  In addition, assume that the beam often has a moisture content around 21%.  You can keep all the original assumptions as the example in class.  Take the time dependent variable for LRFD (λ) as 1.0.  Also assume that bending governs the design and not shear or deflection.  Draw a quick sketch of the beam, supports and loading as…
