Problem 4. A 50-kg block rests on a horizontal plane. At an instant t = 0 s, a horizontal force starts acting on the block. The magnitude of the force varies according to the function F(t) = 96t [N], where t is time in seconds. If the force acts for 7 seconds, what is the velocity of the block? The coefficient of static friction is us = 0.24, and the coefficient of kinetic friction is µ = 0.20.

Solve problem 4 pls

Problem 4. A 50-kg block rests on a horizontal plane. At an instant t=0 s, a horizontal force starts acting on the
block. The magnitude of the force varies according to the function F(t) = 96t [N], where t is time in seconds. If the
force acts for 7 seconds, what is the velocity of the block? The coefficient of static friction is μs = 0.24, and the
coefficient of kinetic friction is μk = 0.20.

Bolts distributed about a bolt circle are often called upon to resist an external bending moment as shown in the figure. The external moment is 19 kip-in and the bolt circle has a diameter of 15 in. The neutral axis for bending is a diameter of the bolt circle. What needs to be determined is the most severe external load seen by a bolt in the assembly. M Neutral axis R NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. View the effect of the bolts as placing a line load around the bolt circle whose intensity FÅ, in pounds per inch, varies linearly with the distance from the neutral axis according to the relation Fb Fb,max R sin 8. The load on any particular bolt can be viewed as the effect of the line load over the arc associated with the bolt. For example, there are 12 bolts shown in the figure. Thus, each bolt load is assumed to be distributed on a 30° arc of the bolt circle. Under these conditions, what is the largest bolt…
