- Q3) A lug wrench is used to tighten a square-head bolt. If 50-lb forces are applied to the wrench as shown, determine the magnitude F of the equal forces exerted on the four contact points on the 1-in. bolt head so that their external effect on the bolt is equivalent to that of the two 50-lb forces. Assume that the forces are perpendicular to the flats of the bolt head. 1"- A 50 lb A C View C Detail (clearances exaggerated) 14" 50 lb 14"arrow_forwardpls help me :( im not too good at thisarrow_forwardA lug wrench is used to tighten a square-head bolt. If 53-lb forces are applied to the wrench as shown, determine the magnitude F of the equal forces exerted on the four contact points on the 1.5 in. bolt head so that their external effect on the bolt is equivalent to that of the two 53-lb forces.

Q4) A commercial airliner with four jet engines, each producing 90 kN of forward thrust, is in a steady, level cruise when engine number 3 suddenly fails. Determine and locate the resultant of the three remaining engine thrust vectors. Treat this as a two-dimensional problem. 4 90 kN 9 m 12 m 12 m 90 kN 9 m 90 kN 1 Good luckarrow_forwardQ2:In the design of the lifting hook the action of the applied force F at the critical section of the hook is a direct pull at B and a couple.

The two handles are connected by pin C and the two blades are connected by pin D. The left blade and the right handle are connected by pin A; the right blade and the left handle are connected by pin B. Determine the magnitude of the forces exerted on the small branch at E when two 80-N forces are applied to the handles as shown.arrow_forwardThe combined action of the three forces on the base at O may be obtained by establishing their resultant through O.
