 Solve the problem. -Find the magnitude of the torque in foot-pounds at point  P  for the following lever:     | \overrightarrow { P Q } | = 5  in. and  | \mathbf { F } | = 20 \mathrm { lb }  A)   \frac { 25 } { 24 } \sqrt { 2 } \mathrm { ft } - \mathrm { lb }  B)   \frac { 25 } { 6 } \sqrt { 2 } \mathrm { ft } - \mathrm { lb }  C)   - \frac { 25 } { 6 } \sqrt { 2 } \mathrm { ft } - \mathrm { lb }  D)   \frac { 625 } { 24 } \sqrt { 2 } \mathrm { ft } - \mathrm { lb }

PQ=5| \overrightarrow { P Q } | = 5 in. and F=20lb| \mathbf { F } | = 20 \mathrm { lb }


A) 25242ftlb\frac { 25 } { 24 } \sqrt { 2 } \mathrm { ft } - \mathrm { lb }
B) 2562ftlb\frac { 25 } { 6 } \sqrt { 2 } \mathrm { ft } - \mathrm { lb }
C) 2562ftlb- \frac { 25 } { 6 } \sqrt { 2 } \mathrm { ft } - \mathrm { lb }
D) 625242ftlb\frac { 625 } { 24 } \sqrt { 2 } \mathrm { ft } - \mathrm { lb }
