Question

(6) The 7-m uniform bar AB weighs 1.8 kN
with its center of gravity at G. The bar is
supported by a ball-and-socket joint at A on
the floor, and the ball end B rests against the
corner of two smooth vertical walls as shown.
For the horizontal 1.6 kN force applied at G
along the x-axis direction, determine (a) the
normal forces from the walls at B (b) the
reaction at support A.
Ans: (a) NBx=1.4 kN, NB = 1.8 kN

The force P = 15 lb is applied to the cable and the cords slip on the smooth surfaces of the non- rotating pulleys. Determine the magnitude and direction of the acceleration of the 36-lb cylinder if (a) the pulleys are massless, (b) the pulleys are 4 lb each. (a = 21.5 ft/sec², a = = 6.9 ft/sec²) P W
A basket of flowers of mass 3 kg is placed on a flat grassy slope that makes an angle θ with the horizontal. The coefficient of static friction between the basket and the slope is 0.45 and the basket is on the point of slipping down the slope. Model the basket of flowers as a particle and the grassy slope as a plane. Take the magnitude of the acceleration due to gravity, g, to be 9.8 m s−2 Express the forces in component form, in terms of θ and unknown magnitudes where appropriate. Write down the equilibrium condition for the basket and hence show that tan θ = 0.45. Determine the angle, in degrees, that the slope makes with the horizontal.

A wrench 1m long lies along the positive y-axis and grips a bolt at the origin (i.e. the wrench can be represented by vector <0,1,0>). A force is applied in the direction of the unit vector <0, 1/sqrt(2), 1/sqrt(2)> at the end of the wrench. Find the magnitude of the force in Newtons (N) needed to supply 5sqrt(2) N*m of torque to the bolt. torque = | r x F | if r = <0,1,0> and F = <0, 1/sqrt(2), 1/sqrt(2)> so the torque is equal to the magnitude of the cross product of these two vectors but I don't understand how to get incorporate the 5sqrt(2) N*m I know that the magnitude of the cross product must be equal to 5sqrt(2) but I am not sure how to work backwards to that answer, please help!.
