An athlete holds a 34.0 N pole in equilibrium by exerting an upward force U with her left hand and a downward force D with her right hand as shown. Point C is the center of gravity of the pole. (Let L₁ = 2.25 m, 42 = 1.35 m, and L3 = 0.900 m. Due to the nature of this problem, do not use rounded intermediate values-including answers submitted in WebAssign-in your calculations.) L3 A B L2 Li C F g (a) What is the magnitude of U (in N)? N -> (b) What is the magnitude of D (in N)? ⑦i

35.0° Dinysics Demos SuDDly Co. The pole is held horizontally by a massless wire under 305 N of tension, connected at a 35° angle. A 8 kg sign hangs from the end of the 4 meter pole. The pole has mass 4 kg. How far away is the wire is attached from the wall? Answer in meters to 3 sig figs.

A uniform plank of length 2.00 m and mass 28.0 kg is supported by three ropes, as indicated by the vectors in the figure below. Find the tension in each rope when a 710-N person is d= 0.500 m from the left end.  Solve for magnitude of T1, T2, and T3.

With complete answer in 4 decimal places and explanation if needed. With understandable writing. Thank u! 1. A uniform ladder of length L is leaning against the side of a building, as shown. A person of mass m = 75 kg is standing on it. The mass of the ladder is M = 10 kg. The coefficient of static friction between the ground and ladder is μs1 = 0.5, and the coefficient of static friction between the wall and ladder is μs2 = 0.3. What is the minimum angle θ so that the ladder doesn't slip?

The cable AB prevents bar OA from rotating clockwise about the pivot O. If the cable tension is 740 N, determine the n- and t- components of this force acting on point A of the bar. 1.6 m B Answers: Tn' i 9 Tt= i II = 1.2 m 61° N N

The flanged steel cantilever beam with riveted bracket is subjected to the couple and two forces shown, and their effect on the design of the attachment at A must be determined. Replace the two forces and couple by an equivalent couple M and resultant Rat A. The couple is positive if counterclockwise, negative if clockwise. 2.19 KN 0.65 m 1.74 m. 75° A Answers: M = i R=( i y 550 N.m kN.m i+ i 0.16 m 0.16 m 1.17 KN j) kN

The arm in the figure below weighs 35.1 N. The force of gravity acting on the arm acts through point A.
