Problem 3: Inputs: a = 12 in b = 12.75 in Table not requ Use the scalar approach (not the cross product). The moment exerted by the weight about point E is 244 lb-in. (a) What is the magnitude of the weight? (round this answer to the nearest whole number) (b) What is the moment exerted by the weight about point S?

4) Determine the total moment caused by the forces Fp4 and Fca about the plate diagonal that goes through point B (the dashed line). Write your answer in cartesian vector notation. FCA= 500 lb 14 ft FRA = 350 Ib FDA= 400 lb 3 ft-> 3 ft 3 ft 2 t 6 ft

Find the Nominal force, N in kilo Newtons (kN). What is the shear force, V in kilo Newtons (kN). Find the bending moment, M in kilo Newton metres (kNm).

1. Please refer to the following vectors:A = 6i + 2j - 3kB = 3i - j - 2kC = -i + j - 4kD = j - 3kE = -i + 2kF = -5kG = 2iH = -3jI = -4i +4j Two airplanes started drifting away from the origin along the directions of displacement vectors {B} km  and {E} km respectively. If vectors B and E are their position vectors in rectangular coordinate system after some time t, what will be their separation distance in kilometers?  2. A ball is speeding up along a circular track. What can be said about the velocity and acceleration vectors on the body? 3. In an intersection, a bus moving at (100i) m/s and a truck moving at (200j) m/s collided with each other. Assuming that the two objects have the same mass, what would be their final speed together?
