A bolt joints shown in fig. The number of bolts Z=2, the bolt the number of bolts z=2 largest of diameter d=16mm, the minor diameter d1=13.84mm, Allowable stress [€] = 100MPa, friction coefficient f=0.1, anti-slip reliability coefficient Kc= 1.2, calculate the maximum load R of the bolt joints.

Atoaster oven has a resistive heating element. the average rate at which it dissipates energy as thermal energy is 1.00 \(\rm kw\). in the united states, emf amplitude in household circuits is \(\mathcal e_{\max}\) = 170 \({\rm \; v}\) and the \(\rm ac\) oscillation rate is 60 \(\rm hz\). part a what is the root-mean-square current through the heating element?
