Wind Load on Mast = 2.27*1*pz T/m length of the mast= 0.245 T/m length of the mast

WIND LOAD CALCULATION (assuming a solid section of 2.27m x 2.27m of the shaft and )

Wind Load on Boom (wind perpendicular to the Boom length)= 1*3*pz T/m length of the mast= 0.324 T/m length of the mast

Wind Load on Boom (wind along the Boom length) = 2.27*3*pz T/m length of the mast= 0.735 T/m length of the mast

Wind Load on Rear Arm (wind perpendicular to the Boom length)= 2.04*1*pz T/m length of the mast= 0.220 T/m length of the mast

Total Wind Load (point load) acting at the top of the Mast (wind perpendicular to the Boom length)= 14.928 T/m length of the mast

Total Moment at the top of the Mast (wind perpendicular to the Boom length)= 250.022 Tm
