Current Attempt in Progress Four forces are exerted on the eyebolt as shown. If the net effect on the bolt is a direct pull of 460 lb in the y-direction, determine th necessary values of T and 0. Assume F₁ = 320 lb, F₂ = 280 lb, F3 = 435 lb, p = 25° F₁ Answers: T = 0= i i F₂ 2 D lb 0 T F₂ X

441. Both pulleys are fixed to the shaft and as the shaft turns with constant angular velocity, the power of pulley A is transmitted to pulley B. Determine the horizontal tension T in the belt on pulley B and the x, y, z components of reaction at the journal bearing C and thrust bearing D if - 0. The bearings are in proper alignment and exert only force reactions on the shaft. 200 min 250 mn 50 N 300 mn 150 mm S0 mm 65 N 80N

The two flexable cables A and N are 220-lb,  When a particle is in equilibrium under the action of forces, Fx=0 and Fy = 0. To solve for the unknown forces, resolve each force into the x and y components and set each equal to zero. Then solve the simultaneous equations to find the unknown F’s. determine the tension in each cable.

The left and right strings have a mass of 0.01 kg, the middle string has a mass of 0.02 kg. Both theta and beta angles are 40 degrees. Show the calculations used to determine the horizontal and vertical components of the tension forces connected to the center string.

V₂ - V₁ = 2 V₂ - V₁ = 1 3 P A modern art sculpture consists of a collar, a spring, and a circular track. The collar has a mass of m = 6 kg and the radius of the track is r = 1 m. If the spring is attached to a point P which is a vertical distance d = 0.3 m away from the perimeter of the circular track (d is measured between point 1 and point P), determine the change in potential energy between state 1 and state 2, and between state 1 and state 3. N The unstretched length of the spring is 0.15 m and the spring constant is k = 85- m UBC Engineering

Q1) A man is pulling a spring of stiffness coefficient 8 Ib/in by his hand with the entire arm held horizontally rotating about shoulder joint O; this force acts at the 21° angle is shown. Determine the force exerted by the deltoid muscle on the upper arm at A and x- and y- components of the force reaction at the shoulder joint. The weight of the upper arm Wu = 4.1 Ib, the weight of the lower arm W1 2.4 Ib, and the weight of the hand WH= 0.9 Ib; all these weights act at the locations shown in the figure. the spring extended 1 in only as shown in figure 1. A tensile force in the deltoid muscle prevents the arm from A- 8 Ibin Equilibrium x-1 in Deltoid muscle Fo A YW, YW -5.2 16.5 25.4 Figure 1

The frictionless slider B has a frictionless pulley mounted to it, around which is wrapped a cable that supports weight W = 180 lb as shown. The pulley at D is also frictionless, and member BE is a bar. If α = 55° determine the force in bar BE.
