A uniform plank is 5.00 m long and weighs 100 N. The cord that attaches to the plank 1.00 m from the bottom end holds it from sliding.  There is no friction between the floor and beam and the wall and beam.  Find the tension in the cord. Hint: Find theta and alpha.  Think about where you will put the axis of rotation.

Answers typed in are incorrect. Tried them many times and they are not right. Please dont give me the same wrong answers marked with a  red X.

1.0m 3.0m 0.5m mi m2 PA N, 5. The drawing above shows two objects on a board supported at two locations. The m; = 40 kg (centered over P), m;=20 kg and m3=10 kg. c. Determine the force exerted by N2. (Take torques around P.) d. m2 rolls to the right. Just before the board starts to tip everything is balanced on N2 with no force on N1. Determine how far to the right of N2 m2 could roll without the board tipping. You might find it easier to take torques around a point rather than P.

A beam with a length of 2 m and a mass of 10 kg supports a 50 kg box. The beam is connected to a wall by a hinge at its base and a horizontal wire. The wire is connected to the beam 1.5 m from the hinge and makes an angle θ of 35o to the beam. The goal is to find the tension in the wire and the horizontal and vertical components of the force exerted by the hinge on the board Calculate the tension in the string. write down Newton’s 2nd law for both x and y directions. find the horizontal and vertical components of the force that the hinge exerts on the beam. Suppose the maximum tension that the wire can withstand is 1500 N. What is the maximum load that the hinge can support before the wire breaks?

A. Draw a different configuration, and make it a diagram similar to Fig. 3. Specifyeach mass and angle you’d be using.B. Determine the tensions T1 and T2 which would be created by each hangingmassC. find the unknown components of T3D.calculate the magnitude and direction of T3

The 60 kg two-wheeled cart is described in the figure and parameter table below, with G indicating the location of the center of gravity. It is to be pulled so that it goes up the small step. Find the normal force on each wheel, and the magnitude and direction of the force applied at handle. HINT: remember that there are two wheels sharing the load @080 BY NO SA 2021 Cathy Zupke 4₁1 G L₁ L₂ parameter value 0.6 0.5 0.8 0.7 0.2 A L3 LA d L3 units m m m m m B L₂ F For the answers, take to the right and up to be the positive directions. The normal force at each wheel at A in the x direction is Ax= 150 XN The magnitude of the force at B is F Measured from the positive horizontal axis, the angle of F= 45 X° = 212 XN
