Esfuerzo Cortante Promedio || Ej. 4 || Factor de seguridad || Problemas 1–90 y 1–91 Hibbeler 8 ed

∞ Enunciados: 1–90. El sistema de suspensión de manejo suave de la bicicleta de montaña está articulado en C y se encuentra apoyado por el amortiguador BD. Si está diseñado para soportar una carga P = 1500 N, determine el diámetro mínimo requerido de los pasadores B y C. Use un factor de seguridad de 2 contra la falla. Los pasadores son de un material con esfuerzo cortante de falla τ_falla = 150 MPa y cada uno de ellos está sometido a cortante doble. 1–91. El sistema de suspensión de manejo suave de la bicicleta de montaña está articulado en C y se encuentra apoyado por el amortiguador BD. Si está diseñado para soportar una carga P = 1500 N, determine el factor de seguridad de los pasadores B y C contra la falla si están hechos de un material con esfuerzo cortante de falla τ_falla = 150 MPa. El pasador B tiene un diámetro de 7.5 mm, y el pasador de C de 6.5 mm. Ambos pasadores están sometidos a cortante doble. 1–90. The soft-ride suspension system of the mountain bike is pinned at C and supported by the shock absorber BD. If it is designed to support a load P=1500 N,, determine the required minimum diameter of pins B and C. Use a factor of safety of 2 against failure. The pins are made of material having a failure shear stress of τ_falla=150 MPa, and each pin is subjected to double shear. 1–91. The soft-ride suspension system of the mountain bike is pinned at C and supported by the shock absorber D. If it is designed to support a load of P = 1500 N, determine the factor of safety of pins B and C against failure if they are made of a material having a shear failure stress of τ_falla =150 MPa. Pin B has a diameter of 7.5 mm, and pin C has a diameter of 6.5 mm. Both pins are subjected to double shear. ∞ Tema: Introducción al Concepto de Esfuerzos: Esfuerzo Cortante Promedio.
