- 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.

If 59-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 1.2 in. bolt head so that their external effect on the bolt is equivalent to that of the two 59-lb forces. Assume that the forces are perpendicular to the flats of the bolt head.arrow_forward
- Determine the force (written as a vector) which BC exerts on member AB (a) if the 820-N load is applied to the center of member AB, and (b) if the 820-N load is applied to the center of member BC.arrow_forward2. A 90 N force is applied at an angle of 30° from the horizontal to the handle of a stroller as shown. Determine the moments of the force about (a) the front wheel and (B) the back wheel.

- The combined action of the three forces on the base at O may be obtained by establishing their resultant through O. Determine the magnitudes of R and the accompanying couple M. Assume F₁ = 350 lb, F₂= 620 lb, F3 = 520 lb, a = 5.4ft, b = 2.9 ft. c = 4.0 ft, and 0 = 50% Answers: R= i 1091.134 lb M= i 9719.344 lb-ftarrow_forwardKindly provide the answer in 3 significant digits and with full solution. Thank you!arrow_forwardRequired information NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. Consider three forces A, B, and C, where A = 165 N, B = 140 N, and C = 225 N. A collar that can slide on a vertical rod is subjected to the three forces shown. C B Determine the required value of a if the resultant of the three forces is to be horizontal. The required value of a for the resultant of the three forces to be horizontal isarrow_forward
