Obtain numerical values for the maximum tensile stress (\(\sigma^+_\max\), in MPa) in the beam, and for the coordinates (\( x_\max,\ y_\max, \) in m) where \( \sigma^+_\max \) occurs:
\[ y_\max = \]
\[ x_\max = \]
\[ \sigma^+_\max = \]
______
\[ y_\max = \]
\[ x_\max = \]
\[ \sigma^+_\max = \]
______
举一反三
- 关系SC(Sno，Cno，Grade)表示学号、课程号、成绩。现要查询最高分在91分以上的学生的学号和平均成绩，正确的语句是______。 A: SELECT Sno，MAX(Grade)<br> FROM SC<br> WHERE MAX(Grade)≥91<br> GROUP BY Sno B: SELECT Sno，MAX(Grade)<br> FROM SC<br> GROUP BY Sno<br> HAVING MAX(Grade)≥91 C: SELECT Sno，MAX(Grade)<br> FROM SC<br> WHERE MAX(Grade)≥91<br> ORDER BY Sno D: SELECT Sno，MAX(Grade)<br> FROM SC<br> GROUP BY Cno<br> HAVING MAX(Grade)≥91
- 已知列表对象x<br/>= [‘11’, ‘2’, ‘3’],则表达式max(x,<br/>key=len) 的值为_。______
- if y>x then max=y: max=x
- 已知A=[1,2,3;-1,-3,2;4,-4,3]，则max(max(A,[],2))=（ ）
- 有如下程序#include [iostream] using namespace std; int max(int x,int y) { int z; if(x>y) z=x; else z=y; return z; } int main() { int a=3,b=5; cout<<"max="<<max(a,b)<<endl; } A: max=3 B: max=4 C: max=5 D: max=6
