Tо receive credit fоr yоur аnswers you must show аll work, including diаgrams, and the appropriate units at each step. 1. (6 pts) A person carries a board that is 8m long with one hand pushing down on it at the right end with a force F1 and the other hand holding it up 51 cm from the right end of the board with force F2. The board has a mass of 10 kg and its center of gravity is at the middle of the board. a. (1.5 pts) Draw an FBD for the board, showing all forces, distances, and indicate a positive direction for torque as well as positive x and y directions. Indicate the right end of the board as the axis of rotation. b. (1.5 pts) With the right end of the board as the axis of rotation, write the summation of torque equation, with all of the torques on the left and zero on the right side. Fill in all known values and fill in logical variable names for unknowns. You do not need to solve it. c. (0.5 pts) Write the second law equation for the vertical direction, just as above, filling in known values and unknowns and putting zero on the right side of the equation. You do not need to solve it. d. (1.5 pts) Now, with the axis of rotation at the left end of the board, write the summation of torque equation, like you did in part b. You do not need to draw a new FBD. You do not need to solve it. e. (0.5 pts) Would it be possible to solve for the 2 unknown forces if you only used the equation in b? f. (0.5 pts) Instead of using equation in b, would it be possible to solve for the 2 unknown forces if you only used the equations in c and d?

CLICK HERE TO SEE QUESTION 1 QUESTION 1 (Rаte, Rаtiо) 1.1 642 691 students in Sоuth Africа are writing the Natiоnal Senior Certificate Examinations this year. 53 185 of them are in the Western Cape. 1.1.1 What percentage of these students is from the Western Cape? (2) 1.1.2 The ratio of boys to girls in Grade 12 in the Western Cape in 2023 is 2:3. Calculate the number of boys in Grade 12 in the Western Cape this year. (3) 1.2 In Grade 12 the Mathematical Literacy candidates write two papers. Each paper is out of 150 marks and the time for each paper is 3 hours. (2) 1.2.1 At what rate should each paper be answered? Give your answer in marks per minute? (2) 1.2.2 How many marks should a student have answered after half an hour? (2) 1.3 In Mathematical Literacy in Grade 12 the CASS mark counts 25% of the final Mathematical Literacy mark. The two examination papers count the same amount towards the final percentage. This is summarised in the table below. CASS 25% Paper 1 A Paper 2 B Total 100% 1.3.1 What is the value of A or B as a percentage? (1) 1.3.2 If a student gets a CASS mark of 68%, what is 68% reduced to a mark out of 25? (2) SUB TOTAL [12]
