Horizontal Bar Puntos:30 A uniform horizontal bar of length L = 2.0 m and weight 136 N is pinned to a vertical wall and supported by a thin wire that makes an angle of 0 = 38° with the horizontal. A mass M, with a weight of 353 N, can be moved anywhere along the bar. The wire can withstand a maximum tension of 548 N. What is the maximum possible distance from the wall at which mass M can be placed before the wire breaks? Enviar Respuesta Tries 0/40 With M placed at this maximum distance what is the horizontal component of the force exerted on the bar by the pin at A? Enviar Respuesta Tries 0/40 With M placed at this maximum distance what is the vertical component of the force exerted on the bar by the pin at A? Enviar Respuesta Tries 0/40
Static Equilibrium of Two Blocks Puntos:40 The system shown in the Figure is in equilibrium. The mass of block 1 is 1.0 kg and the mass of block 2 is 4.2 kg. String 1 makes an angle a = 19° with the vertical and string 2 is exactly horizontal. What is the tension T₁? TI a ml B T2 Enviar Respuesta Tries 0/40 What is the tension T₂? Enviar Respuesta Tries 0/40 What is the tension T3? m2 Enviar Respuesta Tries 0/40 B Enviar Respuesta Tries 0/40 Find the angle ß between string 3 and the vertical. T3
Painter on a ladder -- is it safe? Puntos: 20 A painter wishes to know whether or not he can safely stand on a ladder. The ladder has a mass M₁ = 7.00 kg which is uniformly distributed throughout its length L = 5.80 m. The ladder is propped up at an angle 0 = 71.00. The coefficient of static friction between the ground and the ladder is us = 0.258, and the wall against which the ladder is resting is frictionless. Calculate the maximum mass of the painter for which the ladder will remain stable when he climbs a distance d = 4.50 m up the ladder. Enviar Respuesta Tries 0/40 If the painter does not stand on the ladder, what is the minimum angle 0 for which the ladder will remain stable? Enviar Respuesta Tries 0/40
