",20 O lbin -046.bu R.(200-046 Mc (5200 in 5. Award 10.00 points A concrete foundation mat of 5-m located 4 m from the center of the mat. Determine the magnitude and n esultant of the four loads, where A 280 kN, C 350 D-340 kN, and E- 120 kN (Round the radius supports four equaly spaced columns, each of which is point of application of the inal answer to two decimal places and enter the answer value with the appropriate sign) 280 A. 2D KN The magnitude of the resultant is The point of application zg is The point of application xg is

Explanation / Answer

magnitude of resultant force = 280+350+340+180=1150 kN

zG of resultant force = (280*0+350*-4+340*0+180*4)/1150=-0.59 m

xG of resultant force = (280*-4+350*0+340*4+180*0)/1150=0.21 m
