2. You swing a yo-yo about your head in a horizontal circle, then you swing another one with twice the mass, and twice as fast with the same string. How do the tensions in the strings differ? In what direction must the force (tension) act on the yo-yo? What exerts the force?

Please show your work. Thank you! 61. A woman whose weight is 778 N is poised at the right end of a diving board with a length of 4.51 m. The board has negligible weight and is bolted down at the left end while being supported 3.87 m away by a fulcrum. Find force that the fulcrum exerts in the board. Note: Express your answer in whole numbers. No unit is required for the final answer.

Please include full solution and explanation! And please answer this question right away!!! Thank you so much!

HW1.4. 2D Moment resultant Two forces lying in the x-y plane are defined by their magnitudes and direction angles, as shown in the figure below. Force F₁ has a magnitude F₁ = 360 N, an angle 0₁ = 109°, and acts at point A (310, 0) mm. Force F₂ has a magnitude F₂ = 270 N, an angle 02 = 56°, and acts at point B = (0,385) mm. Determine the total moment about point O due to these two forces. Remember to follow the standard sign convention for clockwise (-) and counter-clockwise (+) moments. y B 10 02 F₂ F₁ A 0₁ X TEGINGEN

11. The following is a problem similar to what Garcia will be working on in statics. You don't have to answer the questions in the original problem – that's a bit beyond what we covered on vectors. But you do have to answer the following two questions: a) Find the vertical and horizontal components of both 60N forces. b) Find the distance between the forces in the positions given, in other words, the distance between the lines running through the two force vectors as shown. Two parallel 60-N forces are applied to a lever as shown. Deter- mine the moment of the couple formed by the two forces (a) by resolving each force into horizontal and vertical components and adding the moments of the two resulting couples, (b) by using the perpendicular distance between the two forces, (c) by summing the moments of the two forces about point A. C 20° 60 N B. 60 N 360 mm 55° 520 mm A O

Please list the given and the formula that had been used. Please complete the prodecure and the solution and the figure. Box the final answer.
