Problem 260 - 261 | Resultant of Non-Concurrent Force System | Engineering Mechanics Review at MATHalino

Problem 260
The effect of a certain non-concurrent force system is defined by the following data: ΣF_x = +90 kN, ΣF_y = -60 kN, and ΣM_O = 360 kN·m counterclockwise. Determine the point at which the resultant intersects the x-axis.

$M_O = 360 \, \text{ kN}\cdot\text{m}$

$60a = 360$

$a = 6 \, \text{ m}$

The x-intercept is at 6 m to the left of the origin. answer

Problem 261
In a certain non-concurrent force system it is found that ΣF_x = -80 lb, ΣF_y = +160 lb, and ΣM_O = 480 lb·ft in a counterclockwise sense. Determine the point at which the resultant intersects the y-axis.

Solution 261

$M_O = 480 \, \text{ lb}\cdot\text{ft}$

$80b = 480$

$b = 6 \, \text{ ft}$

The y-intercept of the resultant is 6 ft above the origin. answer
