The necessary and sufficient requirement for equilibrium of an object that is subject to two-dimensional loading is: O The summation of the forces in the x direction equals zero and the summation of forces in the y direction equals zero. O The forces must be collinear. O The summation of the moments about any point on or off the object is zero. O The summation of the forces in the x direction equals zero, the summation of the forces in the y direction equals zero, and the summation of the moments about any point on or off the body is zero.

I need unique and correct answer. Don't try to copy from anywhere. Do not give answer in image formet and hand writing

Required handwritten answer, Please be sure . Don't provide wrong answer. 1)An engine produces 238 hp at 5872 rpm. If the tractive force of the vehicle produces is 40 lbf, calculate the torque that the engine produces, in ft-lbf, when the vehicle is at constant speed.

Please answer part c and e onwards with working out and answer and please label the parts as you have answered a,b,d

What is the degree of freedom of the two questions

Question 6 a) The bore of each cylinder in a six-cylinder car engine is 45 mm and the stroke for each piston is 125 mm. calculate the cubic capacity of the engine in cubic centimetres (cm³); and calculate the clearance volume per cylinder for a compression ratio, r, of 8.75. b) The bore of each cylinder in a four-cylinder four-stroke internal combustion engine is 38 mm and the stroke of each piston is 165 mm. During testing, the engine runs at 180 revolutions per minute (rpm) with a pressure-volume indicator diagram showing a mean net area of 3.4 cm² and a diagram length of 1.2 cm. The pressure scale on the indictor diagram is set to 150 kN/m² per cm. Calculate the mean effective pressure (m.e.p) and the indicated power developed by this four-cylinder four-stroke engine. c) Figure Q6c shows a pulley system with a suspended load w of 2000 N. Calculate the following: (i) (ii) (iii) (iv) The effort force (FEffort) necessary to lift and hold a load of 2000 N. The ideal mechanical advantage…
