Find the resultant of two forces: A= 150N, acting 30 degrees to left of the y-axis, and B=100N, acting 40 degrees below the x-axis.

Q/ Find the resultant (R) and the direction (N) of the two forces shown in Figure below ? The angle (N) is measured between (R) and the x-axis. O 4 kN 50° 30° y 30° 6 kN Resultant = 6 KN & Direction = 60 O all of the above Resultant = 6.61 KN & Direction = 66.6 Resultant = 6.61 & Direction = 60

The moment of the force F=120 lb about the point O in Cartesian vector form is. F= 120 lb 1 ft 4 ft 2 ft 4 ft Select one: O a. Mo = 200j – 400k O b. Mo = -2007 + 400k O c. Mo = -2007j – 400k O d. Mo = 200j + 400k EN

195 and 745 are separately answered. I am not sure these are correct. please do this carefully.

Find the moments of the forces as shown in figure 3 about point O.

n this question, you will calculate the second moment of area for a 4 ✕ 6 piece of lumber about the x − x and y − y axes, as shown. A rectangle with height h and width w > h is centered on the origin of the x y-coordinate plane. The left and right sides of the rectangle, having height h, are parallel to the vertical y – y axis and the top and bottom sides, having width w, are parallel to the horizontal x – x axis. Visit a hardware store and measure the actual dimensions of a typical 4 ✕ 6 piece of lumber. (Enter your answers in inches.) h = in w = in Calculate the second moment of area about the x − x and y − y axes using the measured dimensions. (Enter your answers in in.4.) Ix – x = ______in4 Iy – y = ________in4
