Question

Each square in the grid is 0.50 mx 0.50 m in dimensions Force F2025 N and a force H-1000MFind the moments of each force about the points A.B.C and D.

Answer 1

$\tau=r\cdot F\cdot \sin\alpha=d\cdot F$ . So,

$\tau_{FA}=1.118\cdot2025=2264\ (N\cdot m)$

$\tau_{FB}=0.2236\cdot2025=453\ (N\cdot m)$

$\tau_{FC}=2.01246\cdot2025=4075\ (N\cdot m)$

$\tau_{FC}=1.118\cdot2025=2264\ (N\cdot m)$ .

Similarly

$\tau_{HA}=949\ (N\cdot m)$

$\tau_{HB}=1897\ (N\cdot m)$

$\tau_{HC}=1265\ (N\cdot m)$

$\tau_{HD}=1739\ (N\cdot m)$
