HW1 and HW2 Q1: Convert: 1-The pressure of SN/mm? to MN/m? 2-The moment of 6000N.cm to KN.m 3-The weight of 2000/b to N, also find the mass in kg and in slag. Q2: The force A = 50N makes an angle of 60° with the x-axis, and the force B = 20N makes an angle of 60° with the y-axis. Find their resultant R and the direction ở with the x- axis by two different ways. Q3: For Fig.1, resolve Force F 150N into components along x and y-axes, also along x and y'- axes. Q4: The resultant of the two forces F and P shown in Fig. 2 is R = 600N, determine the magnitude of force P and the direction 6 of the resultant R with the x-axis. F400N F =150N Fig. 1 Fig. 2 400 Q5: Boom AB is held in position as shown in Fig. 3 by three cables. If the tension in cable AC = 750N, and the tension in cable AD = 100ON, determine: (a)the tension in cable AE if the resultant of the tensions exerted at point A of the boom must be directed along AB, (B)the corresponding magnitude of the resultant. Q6: For Fig. 4, determine the tension that must be developed in the cable of winch puller AB to create a moment of 850N. m about point D. Take d = 2.5m. 65 Fig. 3 Fig. 4 Q7: For the bracket shown in Fig. 5, If the magnitude of the resultant force is to be 80lb along the u-axis, determine the magnitude of Force F and its direction e with the x-axis. Q8: For the angle shown in Fig. 6, if M = 80/b. in, Determine: (a)the equivalent force-couple system at B, then replace this force-couple system by a single force R, and specify the points on the x- and y-axes through which R must pass. 30 lb 12 in 60 50 Ib ----- --- 8 in. 90 b 45 Ib Fig. 5 Fig. 6
