Statics_Tutorial_2_Solution

Hint from professor:  Please remember that in translation the summation of moments of forces is always equal to the moment of the ma vector, not zero. The ma vector originates at G and the sign of the moment of this vector only depends on whether the moment is clockwise or counterclockwise, never on whether a itself is positive or negative. The normal force in problem 1 is never zero and there is no need to use any angle for the force P because the horizontal and vertical components of this force may be determined directly using summations of forces and moments.  Also remember that one may take moments about any point. In practice, one selects a moment point that eliminates the moments of as many unknown forces as possible.

statics, solve question 2

Three coplanar forces act on a point at a certain magnesium point,  the forces which act at the point have the following magnitude and directions 80N force, 0°horizontally to the right,  60N, 110°Anticlock wise from the 80N force and 110N,  225°Anticlock wise from the 80N force.  Calculate the graphical method of the magnitude and the direction of the resultant vector, draw the space diagram before the vector diagram?

Help!!!!! Please answer clearly (numerically)

Note: For all graphical methods, specify all the forces with its appropriate notation, magnitude and angles. Specify scale taken to draw vector diagram. Maintain font sizes appropriately relative to the vector diagram. 1. Three forces are acting on the eyebolt as shown. All forces intersect at a common point. Determine the resultant force (magnitude and direction) using graphical method. iY =3 KN 35° 30 gF3=5KN

1. (Midterm, 2009, Problem 3) Three forces (F1, F2, & F3) acting on the block (1mx1mx2m), and each of the three forces has a magnitude of 1.0N. a. Determine the moment of F1 about point O. Express the result in Cartesian vector notation. b. Determine the total resultant moment of the three forces about point O. Express the result in Cartesian vector notation. Note: You have to treat F2 and F3 as a couple. c. Determine the total resultant moment of the three forces about axis OA (OA is a diagonal of the block as shown from O to A).

Figure 5(a) shows a car seat installation robot. It does the job of three people lifting and installing the seat as shown in Figure 5(b). 8 = 70° and = 50°. The robot exerts the wrench resultant of the forces exerted by the three people. Determine this wrench resultant. Your answer must include the rectangular component (Cartesian) form of the resultant force, the magnitude of the moment collinear with this resultant force and the coordinates of point P on the y-z plane through which the resultant force acts.
