Use the Parallelogram Rule to Find the Magnitude of the Resultant

question 267

Multiple Choice

Use the parallelogram rule to find the magnitude of the resultant force for the two forces shown in the figure. Round to
one decimal place.
-Two boats are pulling a disabled vessel toward the landing dock with forces of $940 \mathrm { lb }$ and $930 \mathrm { lb }$ . The angle between the forces is $25.7 ^ { \circ }$ . Find the direction and magnitude of the equilibrant.

• A) \(182 \mathrm { lb }\) at an angle of \(167.2 ^ { \circ }\) with the \(940 - \mathrm { lb }\) force
• B) \(1823 \mathrm { lb }\) at an angle of \(12.8 ^ { \circ }\) with the \(940 - \mathrm { lb }\) force
• C) \(1823 \mathrm { lb }\) at an angle of \(77.2 ^ { \circ }\) with the \(930 - \mathrm { lb }\) force
• D) \(1823 \mathrm { lb }\) at an angle of \(167.2 ^ { \circ }\) with the \(940 - \mathrm { lb }\) force
