In order to raise the flagpole OC, a light frame OAB is attached to the pole and a tension of 780 lb is developed in the hoisting cable by the power winch D. Calculate the moment MO of this tension about the hinge point O.

In the diagram shown below, the four currents are assumed to be held in place at their current locations. The currents have the following values: IA = 3.000 A, IB = 3.000 A, Ic 1.000 A and ID 2.000 A. Let d = 12.500 cm and assume standard x- and y-axes at point P1. (Be careful about signs!) AO 3d The magnitude of the total magnetic field at point P1, in μT and to three decimal places, is d P1

Four long, parallel conductors carry equal currents of = 1.00 A. The figure below is an end view of the conductors. The current direction is into the page at points A and B and out of the page at C and D. A × C B(x (a) Calculate the magnitude of the magnetic field at point P, located at the center of the square of edge length = 0.200 m. με

Your company is an established engineering contractor for TNB. Your job is to install an underground cable which has two alternatives of sites, A and B. The underground cable with estimation cost of RM 240 per meter will be installed from the TNB 3 Distribution Power Station to the job locations. Details of the factors for the two 14) sites are as shown in Table Q3 below. Table 3: Details of the alternative sites COST FACTOR SITE A 1 km SITE B Average Cabling Distance Monthly Rental Cost for Setting Up and Removal of Equipment Plant Cabling Costs Flag Person Authority Permit 1.5 km RM3,000 RM5,000 RM30,000 RM20,000 RM240/meter RM240/meter RM180 per day N/A RM2,480 RM3,720 The job requires 10,000 meters per km cabling material. Your company is given 12 weeks (6 working days per week) to complete the job. Installed cable will be paid (selling price) RM410 per meter. (a) List fixed and variable costs factor given in Table 3. (b) Calculate all fixed, variable and total costs for both sites…

1 Ropes AB and BC are two of the ropes used to support a tent. The two ropes are attached to a stake at B. If the tension in rope AB is 540 N, determine (a) the angle between rope AB and the stake, (b) the projection on the stake of the force exerted by rope AB at point B
