A) \[175\,\hat{k}\,N-m\]
B) \[150\,\hat{k}\,N-m\]
C) \[75\,\hat{k}\,N-m\]
D) \[25\sqrt{37}\,\hat{k}\,\,N-m\]
Correct Answer: B
Solution :
[b] \[\overset{\to }{\mathop{\tau }}\,=\overset{\to }{\mathop{M}}\,\times \overset{\to }{\mathop{B}}\,=50\hat{i}\times (0.5\hat{i}+3\hat{j})=150\,\hat{k}\,N-m\]You need to login to perform this action.
