 In a jib crane, the jib and tie rod are 5 m and 4 m long respectively. The height of crane post is 3 m and tie rod remains horizontal. Determine the forces produced in the jib and tie rod when a load of 2 kN is suspended at the crane head

the fan has total head of 190 m and A static pressure of 20 cm wg. If the air density is 1.15 kg/m3, what is the velocity of air flowing.

(4x^3-3y^2)dx + 6xydy=0,f(-1)=0

The maximum actuating force on a double short shoe external drum brake illustrated in figure 1 below is 3 kN. If the coefficient of friction for the shoe lining is 0.3. 1.1 Determine the torque capacity of the brake for clockwise rotation of the drum. (11) Hint 1: Note the distance between the shoe and the pivot is not ignorable. Hint 2: Consider both shoes in your analysis. 1.2 Draw the forces acting on each shoe. 

A 10ft long horizontal through has ends in the shape of equilateral triangles. The sides of the triangle are 6ft in length. If water is being poured inside the through, find a mathematical model that expresses the volume of the water as a function of its depth

if the % increase in power required for a helicopter to hover at an altitude above sea level is 6% higher that required to hover at sea level with the same figure of merit, determine the altitude. assume that the density change is 8% per km.

In the manufacturing of an $8 000 car, how much do you estimate is spent on direct labor?

The average Japanese autoworker makes around $8 to $10 per hour and each car at Toyota has about 30 direct labor hours in it. If the average US autoworker makes $20 per hour, how many worker-hours of direct labor are in the typical American car?
