解:
0.78×4320/(153.5)^2×(8337×400)/1138750×(√(1+((153.5×8)/(4.4×400))^2)+0)×1
=0.78×4320/153.5^2×(8337×400)/1138750×(√(1+((153.5×8)/(4.4×400))^2)+0)×1
=0.78×4320/153.5^2×3334800/1138750×(√(1+((153.5×8)/(4.4×400))^2)+0)×1
=0.78×4320/153.5^2×3334800/1138750×(√(1+(1228/(4.4×400))^2)+0)×1
=0.78×4320/153.5^2×3334800/1138750×(√(1+(1228/1760)^2)+0)×1
=0.78×4320/153.5^2×3334800/1138750×(√(1+0.697727^2)+0)×1
=0.78×4320/153.5^2×3334800/1138750×(√1.486823+0)×1
=0.78×4320/153.5^2×3334800/1138750×1.219354×1
=0.78×4320/23562.25×3334800/1138750×1.219354×1
=3369.6/23562.25×3334800/1138750×1.219354×1
=0.143008×3334800/1138750×1.219354×1
=476903.0784/1138750×1.219354×1
=0.418795×1.219354×1
=0.510659×1
=0.510659 答案:0.78×4320/(153.5)^2×(8337×400)/1138750×(√(1+((153.5×8)/(4.4×400))^2)+0)×1=0.510659你的问题在这里没有得到解决?请到 热门难题 里面看看吧!
